HOLLYWOOD, Calif. — Christina Milian is pregnant!

The 27-year-old singer is expecting her first baby with The-Dream, American Superstar has learned.

The pregnancy news comes exactly a week to the day after the pair secretly tied the knot in Las Vegas.

"They are really excited to start their family," said a source, who added that the pregnancy was a surprise to the newlyweds.

Milian and The-Dream got married at midnight at the Little White Wedding Chapel, a venue made famous by Britney Spears' brief marriage to Jason Alexander in 2004.

It was the first trip to the altar for Milian and the second for The-Dream, who was previously married to singer Nivea.

In June, the musical couple held their engagement party in Sin City at the Palms Hotel and Casino. The-Dream, whose real name is Terius Young Nash, popped the question with a six-carat diamond from Ivanka Trump's jewelry line.

Milian and The-Dream, 30, started dating earlier this year.

It remains to be seen what sort of impact the pregnancy will have on the release of Milian's long-awaited fourth studio album, "Elope," on The-Dream's Radio Killa Records. The album had been expected to drop by the end of the year.

"I'm really excited," Milian recently told MTV News. "It's [about] a young female growing into a woman, and it's very honest. The album's fun, so I'm looking forward to performing it."
