Patrick Dempsey on Fame, Family, Grey's Anatomy

McDreamy is no McSteamy, Patrick Dempsey admits.

"I'm not Eric Dane â€" McSteamy is in perfect shape" the Grey's Anatomy star tells the new issue of Parade Magazine. "I definitely have pec envy."

"There's a lot of pressure being a man in this town."

He says his wife of eight years, Jillian, keeps him grounded.

"She always says in the morning, ‘They should see you now!'" jokes Dempsey, who adds that fame "gets very heady ... you've got to be very careful.

"I think I've been managing that well. This is a great opportunity now to really define the next part of my life. I just want to do it right."

Defining the life of Patrick Dempsey these days at home? His daughter Tallulah, 6, and his one-year-old twins, Darby and Sullivan.

"It's like a slapstick routine watching these drunk little men run around because they're so wobbly," he says. "When you see something happen that they couldn't do the day before, it's really heartwarming."

As for what happens tonight with Meredith and Derek? That you'll have to wait and see, although Dempsey says he's "excited" for the couple to finally move forward and grow together.

Patrick and the rest of the Grey's Anatomy cast return at 9 p.m. on ABC. How well do you know the hit medical drama? Follow this link for an exclusive Grey's Anatomy quiz!
