Christina Milian is pregnant with her first child

Christina Milian is pregnant with her first child, Usmagazine.com has confirmed.

The singer, 27, wed music producer The-Dream, 27, on Sept. 4 at the Little White Wedding Chapel in Las Vegas. Us first reported their engagement two months ago.

"The pregnancy was a surprise, but they were getting married regardless," a source tells Us.

Milian has already been talking about children.

"Of course, I would love to have kids," she told Us earlier this summer at the premiere of Bring It On: Fight to the Finish in NYC. "I think that's some of the reasons why I do movies like this."
