Willa Holland (born June 18, 1991) is an American model and actress. Born in Los Angeles, California, the daughter of Darnell Gregorio-De Palma. Holland spent the earlier part of her childhood in London. It was during that period that she spent time on the set of the film Mission: Impossible which was directed by her step-father Brian De Palma.

As of 2006, Willa currently lives in Los Angeles with her two sisters and attends public school.

Holland spent the summer of 1998 in the Hamptons of Long Island with her family. After a day playing at Steven Spielberg's home, the seed was planted that she should spend her life in front of the camera.

Upon her return to Los Angeles that September, Holland first signed with Ford Modeling Agency. She began getting work immediately: her first job was for Burberry of London. She quickly became the top child model in the country working for companies like Guess?, Gap, Ralph Lauren, and many more.

The following year, 1999, De Palma took Holland to a theatrical talent agency. Since then she has shot many national commercials and several movies. She was even slated to co-star in the 2005 FOX series The Inside with fellow model Rachel Nichols, but left the show when writer Tim Minear was brought in to overhaul it. Currently, she has taken over the role of Kaitlin Cooper on The O.C. during the series' third season. She is scheduled to become a series regular next year, for the show's upcoming fourth season.
