Emmy Rossum Goes Topless In "Shameless," Says "Nudity In HD Is Stressful"

NEW YORK (CBS) Actress Emmy Rossum is making a debut of sorts in Showtime's new series "Shameless."

The 23-year-old actress, who plays William H. Macy's precocious 18-year-old daughter Fiona in the show, reveals not only that she'll be naked, but naked "in HD."

"It's my first time being naked on screen so it is definitely a little stressful," says Rossum to RadarOnline.com, adding, "but I think you just gotta rock whatever God gave you and be proud of it."

When the website asked Emmy if she ever worked out with her rock singer boyfriend Adam Duritz of the Counting Crows, the brunette starlet shoots a blush.

"We do work out together," she tells RadarOnline.com. "We run together!"

"Shameless" will start production for Showtime at the end of the summer.
