IT'S HONEYMOON IN VEGAS MEETS KNOCKED UP FOR CHRISTINA MILIAN & THE DREAM!

It's "Honeymoon in Vegas" meets "Knocked Up" for Christina Milian.
When the 27-year-old singer eloped and got hitched in Las Vegas earlier this month to music producer The-Dream it seems she may have been keeping a secret.

A tiny secret.

Seems Milan, who considers herself a role model for young girls, is pregnant.

"The pregnancy was a surprise, but they were getting married regardless," a source told US Weekly magazine.

Milian and The-Dream were engaged for two months. He proposed with a six-carat diamond ring from Ivanka Trump's jewelry line.

Ironically, Milian named her upcoming album, scheduled to be released in early 2010, "Elope."

The two got married Sept. 4 at the infamous Little White Wedding Chapel, the same place where Britney Spears wed Jason Alexander.

Milian's marriage to The-Dream has already lasted longer than Spears' first go-round with maritial bliss, which was shorter than most Vegas hangovers.
