Pregnant Padma Lakshmi: "I Can't Button My Jeans Anymore!"

Top Chef's Padma Lakshmi is feeling the pangs of pregnancy.

"I actually can't button my jeans anymore," she tells Usmagazine.com. "Up until about a week ago, I could. "There's just too much pressure, so I've had to put them away for now."

The 39-year-old Lakshmi -- who struggles with endometriosis, a painful uterine condition that can lead to infertility -- says she hasn't changed her diet.

"I haven't really had any cravings," she says. "There was about a week-and-a- half when I was really craving a cinnamon donut. Then I had the cinnamon donut, and it was like, 'Eh.' I mean, it was ok, but that was it. And then it was over."

Lakshmi -- who isn't revealing the baby's father -- says she's "always been a big advocate of eating what you love and making good choices. That's what I'm still doing now."
