Christina Milian just got married to The-Dream.

Now we know why - they're having A-Kid!

Okay, so they were probably in love and want to spend eternity together and all that good stuff. But the singer-actress has just confirmed she is expecting!

"The pregnancy was a surprise, but they were getting married regardless," a source says of Milian and The-Dream, both 27, who got married last Friday.

Milian has already been talking about children.

"Of course, I would love to have kids," she said earlier this summer at the premiere of her film Bring It On: Fight to the Finish in New York.

"I think that's part of the reason I do movies like this."

The couple, who always seem super happy together, got engaged back in July. No word on whether they plan on naming the little guy The-Dream-Junior.

Regardless, The-Dream (real name: Terius Hagert Youngdell Nash) - who proposed with a six-carat ring from Ivanka Trump's line - has been talking family too.

"I love kids, and [Christina] loves kids probably more than I do," he said. "She'll make that time. In the next couple of years, there'll be something around."
