Newlywed Christina Milian has confirmed that she is expecting her first child with husband The-Dream.

The singer eloped with musician-producer The-Dream – who handled most of the production duties on Mariah Carey’s latest album, Memoirs of An Imperfect Angel, in Las Vegas last month.

“My husband and I are expecting. We’re about four and a half months along, about 19 weeks. We’re really excited,” Christina told PEOPLE at the MGM Grand on Friday night.

The-Dream already has three children with former wife Nivea.
