The course of true love never did run smooth, but even Shakespeare himself would be stunned by roller coaster relationships that the A-list embroil themselves in.
From the dirtiest love rats to crawl out of the sewers of betrayal to cradle snatchers who are this close to having to sign a register, Hollywood has them all.
So, in honour of Valentine's Day take my hand and waltz through the the most scandalous celebrity relationship misdemeanours!
Category One: Creepy Cradle Snatchers
Doug Hutchinson and Courtney Stodden
Marrying a 16 year old and they paying for her to stuff herself to bursting point with silicone might seem immoral to some people, but don't worry. God was totally into it!
Hutchinson said that "God connected us. When you meet that someone you love, there's something inside that's leading you towards that person" after his controversial engagement to his child bride.
Alas, what the Lord giveth the Lord taketh away. To absolutely nobody's surprise Stodden and Hutchinsons relationship dissolved at the tail end of 2013.
Woody Allen and Soon-Yi Previn
crossed all sorts of murky boundaries when he announced at the age of 56, he was marrying 21-year-old Soon-Yi. It wasn't just the age difference that had the press recoiling in horror though. Soon-Yi was his girlfriend of 10 years, 's adopted daughter.
Farrow discovered the shocking affair after stumbling across a stack of naked photos of Soon-Yi in Allen's study. Despite the controversy that surrounds their relationship, Allen can see nothing wrong with his behaviour and he has been recorded saying;
What was the scandal? I fell in love with this girl, married her. We have been married for almost 15 years now
Allen's biological son, sees things differently though. The government official has famously said;
He's my father married to my sister. That makes me his son and his brother-in-law. That is such a moral transgression
Sam Taylor-Johnson and Aaron Taylor-Johnson
When 42-year-old was chosen to direct Nowhere Boy in 2009, the last thing the public imagined was her whirlwind engagement to the 19-year-old star .
Johnson went from playing the brother of Taylor-Woods daughter, Angelica on screen to effectively becoming her Stepfather in real life with lightning speed. The young star was engaged to Taylor-Wood by the time Nowhere Boy premiered.
Some might say the couple were hasty, but when interviewed in November 2009 and asked if her relationship with Johnson feels like it's forever, Taylor-Wood candidly answered "Yeah, it does".
Maybe she was right because the pair have since had two daughters together and they tied the knot in 2012. Awwwwwwwww!
Category 2: Flashes in the Proverbial Pan
Kristen Stewart and Rupert Sanders
Shattering the hearts of millions of Twihards with one fell slip of her lips, endured a spell as public enemy number one thanks to her short lived affair with Snow White and the Huntsman director, Rupert Sanders.
' marriage to crumbled to dust as a result and, although took KStew back for a while, things were never as sparkly between the pair again. Boo hoo!
Arnold Schwarzenegger and Brigitte Nielsen
Most people would be shouting from the rooftops about doing the dirty with , but managed to keep his lips sealed until 2012!
Arnie and Nielsen have both admitted to getting it on on the set for Red Sonja in 1985 when Nielsen was married to and Schwarzenegger was living with his wife-to-be, Maria Shriver.
Clearly time really is a healer because Stallone and Schwarzenegger are still working together on The Expendables 3. Bros before hos!
Meg Ryan and Russell Crowe
looks like she barfs up sunshine and rainbows for fun. but back in the mists of time, she had an affair with the hunky . After nine years of marriage, it looked like her relationship with was going to withstand the pressures of Hollywood drama until Crowe-ageddon broke, but radiant Ryan had her reasons.
in 2008 Ryan explained to tabloids that Quaid had been sewing his wild oats with all of sundry the entire time they were together. His subsequent wife also ditched him for adultery, so maybe Dennis is the dodgy one...
Claire Danes and Billy Crudup
I don't believe had the audacity to look so damned sweet in those Romeo And Juliet angel wings! The actress and her Stage Beauty co-star had an affair that was sparked off on set in 2004, but Crudups wife also happened to be pregnant. Very pregnant.
Future Weeds star, Mary Louise Parker was served divorce papers from her love-rat husband when she was SEVEN months pregnant with his child. Danes and Crudup enjoyed each other's company for two years before the actress ran away with her current husband, , in another steamy affair. Naughty!
Caregory 3: Down Low Lovers With Sticking Power
LeAnn Rimes and Eddie Cibrian
and Eddie Cibrian plummeted the phrase 'keeping it classy' to previously unplumbed depths with their naughty little affair. Not only did the pair meet on the set of an ultra-sophisticated Lifetime movie, they also both betrayed their spouses.
Understandably, Brandi Glanville, 's ex-wife was not happy, but because the couple have children together she kept things sensible and mature.
Oh no wait, no she didn't! She ended up having a long drawn out and passive aggressive Twitter war with Rimes instead for over a year. How sweet.
Cibrian and Rimes still appear to be going strong despite the outward pressures, so maybe these two truly deserve each other!
Tori Spelling and Dean McDermott
Who knew Lifetime TV movies were quite so irrepressibly arousing. and fell slobbering into each others arms on the very night they met on the set of Mind Over Murder. Ooh la la!
The pair married less than a month after the ink of Spelling's divorce papers from former husband, Charlie Shanian had dried, but karma is a bitch.
Their marriage is reportedly in tatters after McDermott checked into rehab after confessing to cheating with more than five other women. As if that wasn't enough, a source has also let slip that;
Dean admitted to not always using protection during the encounters. It’s the ultimate betrayal for Tori and she probably won’t be able to ever forgive him for that. It’s one thing to cheat, but another to have unprotected sex
Ewwwwwwwww. Just ewwwwwwwww. Maybe this pair won't be in this category for much longer...
Elizabeth Taylor and Richard Burton
People need to burn ideas that everyone was more honorable in the 'good old day' because and were tearing shit up before you were even born.
These star crossed lovers met on the set of Cleopatra in 1963 and were consumed by a furious passion that devoured their previous marriages without mercy. The pair did not seem to mind the absolute scandal of their union and continued to court booze-fuelled controversy wherever they went.
The pair married and divorced twice and exchanged barbed insults and diamonds in equal measure, but they could never quite purge each other from their lives.
Before his death, Richard supposedly told a close friend that despite all the years Taylor 'still fascinates, you know'. While a much older Elizabeth waxed poetic and told people that if Richard had lived, she was sure they would have married again.
When asked to explain why they just couldn't ever seem to make it work Elizabeth answered
Maybe we loved each other too much
I'm sure that 'maybe we drank too much' would be an equally valid answer, but it is sweet none the less!
Bradd Pitt and Angelina Jolie
Ah , UN ambassador, adoption advocate and homewrecking succubus! When the press started spreading rumors that had been cheating on his former wife, with Angelina on the set of Mr. & Mrs. Smith all hell broke loose.
The pair admit that they "fell in love" on set but Jolie told the press that "To be intimate with a married man, when my own father cheated on my mother, is not something I could forgive. I could not look at myself in the morning if I did that. I wouldn't be attracted to a man who would cheat on his wife".
Whatever happened, the result was a jubilant media circus. Aniston was patronisingly cast as a perpetually downcast martyr, Jolie as the impenetrable ice queen seductress and Pitt as love rat of the century.
Few would say, 9 year later, that Jolie and Pitt made the wrong decision though. The pair have six children together and their first biological child was named by the Associated Press as "the most anticipated baby since Jesus Christ".
And, they still look totally sweet on each other. Check out this sparkly little look of love!
Category 4: Crazy in love
Katie Holmes and Tom Cruise
If she's good enough for Xenu she's good enough for Tom! Oprah sofa moment aside, the beginning of and ' relationship seemed like plain sailing, but when the couple split in 2012 the black Scientology slime began to spill out with gusto.
It has been widely rumored that officials at the Church of Scientology handpicked Cruise's bride for him through extensive 'auditing' to assess her suitability for the role. Rumors have also surfaced about a lucrative 'marriage contract' that involved enormous payments to Holmes for every year the couple stayed together and, for each child they had.
Cruise himself has now admitted that Holmes fled from their marriage due to her concerns about Scientology and its influence on their young daughter, Suri.
Who knows what went on behind closed doors...
Charlie Sheen and Brooke Mueller
When two clouds of madness collide they come together to make a toxic gas that suffocates everyone around them and, creates some brilliant Twitter wars to boot.
and were married in 2008 and it didn't take long for the problems to bubble out of the septic tank of their hasty romance. Not surprisingly considering Charlies accidental shooting, knife wielding, wife punching past he was arrested for assaulting Mueller on Christmas Day in 2009.
A year after he decked his wife (maybe he was high enough to mistake his fists for bows of holly?) he filed for divorce, but it is after their official split the madness mobile went full throttle. Mueller was forced to get a restraining order in which she claimed he had gone insane in 2011.
Sheen sensibly responded by proving to the world he was a logical and rational being with a series of Tweets like these:
Brilliant! Bet you can't beat that for nightmare ex behaviour!
Can you guys think of any scandalous celebrity love life moments I have left off my list? Who do you think is the biggest bottomfeeder?
