Newlywed CHRISTINA MILIAN is expecting her first child with husband THE-DREAM, according to a new U.S. report.

The Dip It Low singer stunned fans by secretly marrying the producer/singer in Las Vegas last week after a whirlwind romance, and according to UsMagazine.com, there's another surprise in store - Milian is pregnant.

But insiders claim the marriage wasn't a result of the pregnancy.

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

It will be Milian's first child, while The-Dream, real name Terius Nash, has a four-year-old daughter and two young twin boys from his previous marriage to R&B singer Nivea.

He split from Nivea in 2007 after a three year marriage.
