Taylor Michel Momsen was born on July 26th, 1993 in St Louis, Missouri to parents Michael and Colette Momsen. She began acting professionally at age three, with a national commercial for Shake ‘N’ Bake. She first landed the role of Honey Bee Swan in The Prophet’s Game (1999). Her first big role was as Cindy Lou Who in ‘Jim Carrey’’s How the Grinch Stole Christmas (2000). After that, Taylor landed the role of Julie Moore in We Were Soldiers (2002) which also starred her younger sister, Sloane Momsen. She got parts in two more motion pictures: Hansel & Gretel, in which she played Gretel, and Spy Kids 2: Island of Lost Dreams, in which she played Alexandra, the President’s daughter.

Taylor’s career came to a halt for over three years until she got the lead role in the never-aired WB series Misconceptions. In 2002, Momsen recorded “Rudolph the Red-Nosed Reindeer” & “One Small Voice” featuring Myra & Camille Winbush for School’s Out! Christmas.

Momsen appeared in the 2006 film Saving Shiloh and as Molly in the 2007 Walt Disney Pictures film Underdog.

She currently plays the character of Jenny Humphrey in the CW television series Gossip Girl, which is based on the book series by Cecily von Ziegesar.

In June 2008, at the age of 14, Momsen signed to IMG Models.
