She’s the little girl with the glittery jeans who stole Sam’s heart with her rendition of "All I Want for Christmas Is You" at the end of the 2003 holiday smash Love Actually, but whatever happened to the musical goddess Joanna? Turns out she’s the stunning 23-year-old Olivia Olson, a voice actress for hit cartoons like Adventure Time and Phineas and Ferb.
Her show-stopping performance in Love Actually was her only noteworthy live-action role, but Olson’s career hasn’t slowed down. In addition to her cartoon work, she’s also a singer-songwriter who posts videos of her music online.
In December 2012, she and pal Clay Priskorn posted a YouTube clip of them performing their original tune “Speak Up,” which shows off Olson’s still-killer vocals.
Olson’s dad, Martin Olson, is a writer for Phineas and Ferb, and has garnered four Emmy nominations for his work on the animated series. In June, she posted an Instagram video of herself and her dad singing the Adventure Time song “Daddy, Why Did you Eat My Fries.”
“God (or satan) must have had a plan sticking me in your path. I am so lucky so be able to work side by side with this man & travel the world doing what we've done since before I could talk,” she captioned the clip. “Happy Father's Day to all the Dad's out there who give a damn.”
