"Let me tell you something, my babies weigh six pounds each, that's 12 pounds just of baby right now and I still have miles to go before I sleep -- with them," Roberts said in the first interview since she was hospitalized Oct. 23 in Los Angeles after experiencing contractions.
Roberts and her husband Danny Moder are expecting twins in January -- a boy and a girl.
"They're huge, they're bionic, it's pretty amazing. My stomach is enormous and the bigger it gets the smaller my ass looks so I'm kind of enjoying it."
There have been reports that Roberts and Moder have registered on an online baby gift registry for expectant couples.
"I'm not registered for anything, I don't have a baby registry," she said.
