"Grey's Anatomy"'s summer hiatus is over, party people.

The cast reported to set for their first day of work this morning and executive producer Shonda Rhimes is already tweeting about it.

She's even sharing photos, like this one of Ms. Callie Torres (Sara Ramirez) in full Seattle Grace wardrobe.


Excited for the fall season?

Any strong, lingering feelings about the fact that Callie's ex man, Mr. George O'Malley (T.R. Knight), won't be returning?

Any reaction to the news that "X-Files" vet Mitch Pileggi will be reprising his role as a member of the hospital's board of directors for the premiere?
