Sarah Michelle Gellar: 'Late Show With David Letterman'!

Sarah Michelle Gellar wears two different outfits outside The Ed Sullivan Theater on Monday (Febraury 6) in New York City.

The 34-year-old actress taped an appearance on The Late Show With David Letterman to promote Ringer, which returns Tuesday (February 7) at 9/8c on the CW.

SMG takes on the role of twins Siobhan and Bridget in the drama, which also co-stars Ioan Gruffudd, Nestor Carbonell, and Kristoffer Polaha.

“The conceit of having Siobhan in Paris was perfect for the first chapter, but we wanted to amp things up and it’s just more fun playing with the twin-ing of it all by having the two sisters in the same city simultaneously and kind of interacting and interweaving [and] at least from one side, unaware,” Ringer co-creator and executive producer Eric Charmelo recently told a group of reporters (via Access Hollywood).

FYI: SMG is wearing DL1961 Premium Denim Emma waxed leggings. She accessorized with MEUS Designs and J/Hadley jewelry.
