Now that Grey’s Anatomy has been spun off with the creation of the upcoming Private Practice, both medical series are getting beefed up with additional faces in their regular casts.

Grey’s Anatomy fans can expect to see Chyler Leigh, who played Meredith Grey’s (Ellen Pompeo’s character) half-sister, Lexie, in the final two episodes last season. Leigh has been added to the show’s regular cast when it resumes. She was initially reported to have been tapped for just thirteen episodes but has now been included in the entire fourth season. Her permanent inclusion should pose much tension and excitement judging from the sparks that flew between her character and Patrick Dempsey’s Dr. Derek “McDreamy” Shepherd. The chemistry between them had already generated some conflict between Derek and Meredith in Lexie’s brief turn last season so it would be interesting to see what kind of havoc she might wreck for an entire year.

Chyler Leigh had previously appeared in such popular television shows as 7th Heaven, That `80s Show, The Practice and Reunion as well as the film, Not Another Teen Movie, with Jamie Pressly, Lacey Chabert, Chris Evans and Mia Kirshner.

The Grey’s Anatomy cast and crew return to film their fourth season today.

In similar news, Grey’s Anatomy spin-off, Private Practice, has also added KaDee Strickland to its regular ensemble cast of characters. Strickland will portray an administrator at the Oceanside Wellness Center. Prior to joining Private Practice, Strickland appeared in the films The Sixth Sense, Girl, Interrupted, Something’s Gotta Give, The Stepford Wives and Anacondas: The Hunt for the Blood Orchid. More recently, she was in The Grudge starring Bill Pullman and Sarah Michelle Gellar, as well as in Fever Pitch, featuring Drew Barrymore and Jimmy Fallon. On television, Strickland guest-starred in Law & Order: Criminal Intent and co-starred with Teri Polo in The Wedding Bells.
