We're all guilty of having done it at some point, but it seems that if you're a celebrity couple, laying on public displays of affection and parading your love around with your significant other is basically regarded as part of the job description these days.
At awards ceremonies, in cafes and restaurants, on the beach, out on the city streets, on Instagram accounts, we've all seen our fair share of A-lister tonsil tennis over the years. And while we may agree that it's all very cute, leaving us third wheeling in on the sizzling action and twiddling our thumbs can be quite awkward.
Yet, which celebrity smooch really takes the biscuit when it comes to PDA? Check out these over-the-top kisses and decide for yourselves:
1. Britney Spears & Madonna
MTV VMAs 2003. Never forget.
2. Kim Kardashian & Kanye West
The whopper that was Kanye's 'Bound 2' video sent shockwaves through the internet. If you've ever wanted to envision Kim full-on getting it on with her husband, here's your chance:
3. Gene Simmons & Shannon Tweed
Putting that tongue he's known for to good use!
4. Wiz Khalifa & Amber Rose
Is this how the kids these days kiss?
5. Jessica Simpson & Eric Johnson
Thanks for sharing with us how you spent your Valentine's Day guys!
6. Scarlett Johansson & John Travolta
I think everyone, ScarJo included, was very confused as to why exactly this incident happened.
7. Jennifer Aniston & John Mayer
Looking back, I bet Jen's quite glad that one didn't work out!
8. Madonna & Drake
The Madge strikes again... this time at Coachella. Sadly, it seems that Drake wasn't quite as into it.
9. Mariah Carey & Nick Cannon
"Just close your eyes honey, and hope that it all works out."
10. President Obama & Michelle Obama
He's the most powerful man in the world. He can kiss how he wants.
11. Gerard Butler & Morgan Brown
Yep, there's Gerard Butler... grabbing his girlfriend's butt.
12. Chris Pratt & Anna Faris
They. Are. Perfect.
13. Alec Baldwin & Hilaria Baldwin
Sure, go ahead Alec and ignore the 40 cameras that are behind you.
14. Sandra Bullock & Meryl Streep
Wrong on so many level, but the fact that this even happened at all at the 2010 Critics' Choice Awards is absolutely awesome!
The guy in the background loves it, as do we.
15. Chris Hemsworth & Elsa Pataky
They are so cute it hurts.
16. Tyra Banks & Bow Wow
Are they even dating? Who cares, this is great!
17. Nicole Kidman & Keith Urban
Ummm... sorry are we intruding on a special moment here?
18. John Legend & Chrissy Teigen
If there was an award for the most loved-up couple at the 2015 Golden Globes, these two would get it.
