The former Miss California USA is expecting her first child with husband Kyle Boller, the Oakland Raiders quarterback, she confirms to Fox News.
"We are just so excited," says Prejean, 23. "I'm due in May on my grandmother's birthday. She recently passed away, so that's very special to us."
The couple, who got married this summer, will find out the sex of the child next week, and are already thinking about names – though they're keeping their ideas under wraps so far.
For now, Prejean is just trying to deal with the pregnancy symptoms. "I'm trying to stay healthy, but it has been tough," she says. "I've been getting night sickness."
For his part, Boller, 29, says he's ecstatic. "I have the most beautiful pregnant wife ever, we are so in love, and this was just the best news when we found out a couple of weeks ago," he says.
Prejean shot to fame in 2009, when she voiced her opposition to gay marriage during the Miss USA pageant. She ended up as the first runner-up, but was later stripped of her Miss California title for allegedly violating her contract.
