Olson moved into the mainstream with her role as Joanna Anderson in the 2003 holiday film Love Actually, singing the song ' All I Want for Christmas Is You'. Olson has appeared as a singer and actress on television shows and in live theatre, including Comedy Central Stage, the HBO Theater, and The Fake Gallery.

She is of Afro-Jamaican descent through her biological father. Olson graduated from Agoura High School in 2010. She lives with her father, Martin Olson, mother Kay Olson, and brother Casey Olson. Olson was adopted at birth and raised in Los Angeles, California. She also played the character of Joanna in the 2003 film Love Actually and its 2017 short sequel Red Nose Day Actually.Īlong with this, she is also a writer, having written the Boom! Studios graphic novel Marcy and Simon, co-authored Adventure Time: The Enchiridion and Marcy's Super-Secret Scrapbook, and contributed writing to the best-seller Adventure Time Encyclopedia' for Cartoon Network. The catchy song made it sound a lot like the two characters were once a couple, which seemed further verified when the item stolen from Princess Bubblegum turns out to be a T-shirt from Marceline that the princess sleeps in each night.Olivia Rose Olson (born May 21, 1992) is an American actress, singer-songwriter, and writer, largely known for her voice roles as Vanessa Doofenshmirtz in Phineas and Ferb and Marceline the Vampire Queen in Adventure Time.

When Bubblegum objects, Marceline launches into a song that sarcastically apologized for not treating Bubblegum like a goddess, asked if Marceline was not sweet enough for her, and proclaimed that Marceline shouldn't have to prove anything to her. This speculation kicked into high gear after the third season episode 'What Was Missing.' A mysterious creature steals personal items from different characters and then hides behind a door that can only be opened by a 'song from a genuine band.' The characters form an ersatz band, and veteran singer Marceline starts singing a breezy song about sucking the color off of Princess Bubblegum's face. One of the longest-running areas of discussion surrounding Adventure Time is whether Marceline the Vampire Queen and Princess Bubblegum were ever a couple in the past.
