That Gorgeous Little Girl from 'Love Actually' Is All Grown Up

In 2003, Love Actually took cinematic cuteness to a new level when an adorable character named Sam chased after his young crush Joanna in the airport so he could profess his love. Now, Joanna is all grown up and totally blowing our minds.

Olivia Olson was just 11 years old when she starred in the feel-good holiday flick and wowed us with her rendition of Mariah Carey’s “All I Want for Christmas Is You.” At 23, she can still carry a tune.

Olson posts tons of singing videos to her YouTube channel that has more than 19,000 subscribers. In 2013, the former child star and L.A. native released her debut EP, “Beauty Is Chaos.” Today, she provides the voice of Marceline the Vampire Queen for Cartoon Network’s “Adventure Time,” as well as Vanessa Doofenshmirtz, a character in Disney’s animated series “Phineas and Ferb.” Olson’s “Love Actually” co-star and onscreen love, Thomas Brodie-Sangster, also works on the show, voicing Ferb.
