Sarah Michelle Gellar got to work on her new CW series, Ringer, yesterday in LA. Sarah Michelle revealed a flash of leg in a sexy, slitted skirt as she shot scenes with some of her costars. A preview of Ringer was released in May, giving fans a sneak peek at SMG's dual role as twin sisters with very different personalities. She also took the much-anticipated project to Comic-Con last month and hinted that her husband, Freddie Prinze Jr., could make a cameo in an upcoming episode! Sarah Michelle split her Summer between family time with Freddie and their daughter, Charlotte, and taping her return to the small screen, which we'll get to see when it debuts Sept. 13.
