Joanna Anderson's spine-tingling rendition of 'All I Want for Christmas' in Love Actually is one of the biggest emotional sucker punches that the iconic romantic comedy has to offer, and the singing sensation behind the adorable scene is still making sweet music over a decade later.
As if the performance above weren't impressive enough, Olson was actually so incredible at singing that she had to be trained to sing "less technically" in order to make the concert more raw and believable.
The 11-year-old girl with the spectacular voice, Olivia Olson, is now a talented 23-year-old and she has been busy carving out an impressive career for herself since making our hearts melt all those years ago.
Although you might not have seen Olson's face in anything since Love Actually, she is still hard at work as a voice actress and is responsible for breathing life into the Marceline The Vampire Queen in Cartoon Network's cult classic Adventure Time.
You might also recognize Olivia's voice from her work as Vanessa Doofenshmirtz in Disney's Phineas and Ferb.
Just like a lot of us, Olson clearly can't get enough of the wild adventures of Finn and Jake and her Instagram account is bursting at the seams with cute Adventure Time posts to prove it.
And she has a killer Black Milk collection to make any Adventure Time fangirl seriously jealous.
Olivia also continues to perform as a singer/songwriter and she released her debut EP 'Beauty Is Chaos' in 2013 and you can check out how much her soulful voice has matured in the video below:
