'Grey's' star joins Screen Gems musical

“Grey’s Anatomy” star Eric Dane will round out the ensemble cast of Screen Gems’ upcoming musical “Burlesque.”

Cher, Christina Aguilera, Stanley Tucci, Cam Gigandet, Kristen Bell, Alan Cumming and Julianne Hough have already boarded the project, written and to be helmed by Steve Antin.

Donald De Line will produce via his De Line Pictures banner.

Story centers on Ali, an ambitious small-town girl with a big-town voice (Aguilera) who finds love, family and success in a neo-burlesque club. Dane will play Marcus, a charming, successful businessman who offers to buy Tess (Cher) out of the burlesque club and vies for Ali’s heart.

Lensing began Nov. 9 in Los Angeles, and the pic is scheduled to be released for Thanksgiving 2010.

Dane’s recent film roles include “Marley and Me” and “X-Men: The Last Stand.” He will next be seen in New Line’s romantic comedy “Valentine’s Day.”

He is repped by CAA and Management 360.
