Tina Fey is on the cover of the May Marie Claire, on newsstands next week.
The 37-year-old "30 Rock" writer/producer/actress star jokes about playing pranks like George Clooney and Matt Damon, motherhood and what she did during the writers' strike:
On playing pranks with SNL comedienne Amy Poehler on the set of her new movie Baby Mama:
"We love pranks. I mean, we're kind of like Cloons and Damon that way, doing a lot of, like $250,000 pranks. I did a really funny prank where I got my assistant to paint all the cars in your neighborhood white so you would wake up and think it was snowing. That was a good one."
On what she did during the writers' strike:
"I worked out three times. Well, I went to the gym three times, but I only worked out two of the times. One other time I used the bathroom. Actually, I spent the whole time with my kid, which was nice. It was like the maternity leave that I never got. She is now able to pick me out of a lineup of four or five women."
On good advice from her mother:
"Always wear a bra. Whether you think you need it or not, just wear one. You're not going to look back and regret it."
"30 Rock" is back with new episodes starting tonight.
