"I'm definitely going to have some, I'm sure," the actress, who turns 30 on July 1, says in the July issue of Allure. "Especially when you see what happens to your body after you have a baby."
After her son Milo was born in December 2004, Tyler says, "I was trying to get back into shape, so I went to the gym every day, sometimes twice a day."
But looking good is part of the job – Tyler models for Givenchy and stars in this summer's thriller The Strangers. "I have to make a living," she says. "I guess I could sell my house and go live a really simple life in a trailer somewhere."
But as the famous daughter of famous parents (Aerosmith's Steven Tyler and model Bebe Buell), she's pals with other second generation celebs, including Kate Hudson, whose son Ryder, 3, has playdates with Milo.
Tyler and Hudson also played lovers in the 2000 movie Dr. T and the Women. "She plays a woman who is about to get married, and she's completely in love with me," Tyler tells Allure.

Even as a teen, Tyler never tried to push the envelope. "I never had that much to rebel against because my parents were always so kind of cool," she says. "I mean, what could I do? Run away and smoke a joint and go to rock concerts for the weekend? I mean, that's all they ever did."
Instead, she says, "I've always been super-responsible and hard-working and kind of a worrier."
