Former O.C. star Rachel Bilson is heading back to TV as a doctor in a new drama series.

The Jumper actress returned to the small screen last year for a guest part in hit sitcom How I Met Your Mother, but she has now signed up for a more permanent role in upcoming show Hart of Dixie, about a New Yorker practicing medicine in a small Southern town.

It is Bilson's first big TV project since The O.C. came to an end in 2007.

The show will premiere on America's CW network later this year.
