James Lafferty returns for a fourth season in the hit drama, "One Tree Hill," as Nathan Scott, the favored son of Dan Scott (Paul Johansson) and half-brother to Lucas (Chad Michael Murray).

Born and raised in Hemet, California, Lafferty spent much of his childhood hanging out with friends and his younger brother, Stuart, taking acting classes and playing basketball, his two passions in life.

Lafferty successfully balanced a high school education and starting spot on his varsity basketball team with his burgeoning acting career, landing a starring role opposite Ron Pearlman in the independent feature "Boys on the Run."

The sitcom "Emeril" gave Lafferty his first series regular role as the son of Emeril's character. He followed that up with ESPN's "A Season on the Brink." Lafferty's role in the film was a prelude to his "One Tree Hill" role, since he was able to first showcase his basketball prowess in front of the cameras. Starring opposite Brian Dennehy, Lafferty played Steve Alford, the star player of the Indiana Hoosiers basketball team. He has also made guest appearances on "Once and Again," "Boston Public" and most recently, HBO's "Unscripted."

Currently living in Wilmington, North Carolina, Lafferty has been working on film projects set up through his production banner while continuing to film "One Tree Hill." He has hosted numerous charity basketball events for local organizations and schools in the Wilmington area. Lafferty has also lent his support to other charitable organizations recently, including Lamar Odom's Music Jam and The Pink Project. When he isn't working, Lafferty spends time with his friends and his dog Nino on his boat.

Born and raised in Pasadena, California, Bush started her career on her high school theater stage. Having been crowned the Pasadena Rose Queen, Bush quickly attracted attention from Hollywood.

Bush is an avid scrap-booker. She enjoys photography, reading and spending time with her friends.
