Willa Holland plays bad girl Kaitlin Cooper in hit TV show "The O.C", in which she stars as Mischa Barton's character, Marrisa's little sister. Rachel Bilson Adam Brodyand Benjamin McKenzie also feature in the show.

With top movie-director Brian De Palma as her step-father, it was almost inevitable that Willa would end up working in the entertainment industries. When she was a child, the Los Angeles born star got a taste of life in showbiz when she spent time on the set of Tom Cruise movie "Mission: Impossible", which was directed by her step-father. Plus in 1998, she spent a day playing at Steven Spielberg's home, which kept her wish to perform burning inside her.

Willa's own career in the entertainment industry started when Brian spotted her star potential when she was seven-years-old and took her along to a talent agency. Her distinctive looks won her modeling work for top clothing companies Burberry, Guess, Gap, Abercombie & Fitch and Ralph Lauren, quickly establishing her as a top child model.

As well starring in "The O.C", Willa has appeared in episodes of "The Comeback", and featured in the movies "Ordinary Madness" (2001) and "The Heart Is Deceitful Above All Things" (2004)

The brown-haired, green-eyed starlet is also involved with charity projects, and features in a new promotional campaign video for anti-drugs organization, The Montana Meth Project.
