"We know the sex of our baby. We can now narrow down the names to just one gender," Rycroft, 27, said Friday in Orlando, People magazine reported.

"I'm not telling. It's a secret," she said.
Rycroft said she's having an extraordinarily easy pregnancy.
"Pregnant cravings are the one thing that I really want to experience, and I'm not. My doctor says sometimes people don't get to experience it. I have no cravings, no aversions, smells don't bother me, no morning sickness, none of that. I've really gotten lucky. Not even heartburn.
"All I've got is the belly. I like it. I was nervous about what my body was going to do, but I try to eat healthy and maintain somewhat of a workout schedule so that the weight I put on is a healthy weight. So far, it seems to be working for me," Rycroft said.
