Big news from Alicia Keys: she's going to be a mom!

Following much speculation, a rep for the Grammy winner confirms to UsMagazine.com that Keys, 29, and producer beau Swizz Beatz are expecting a baby and are engaged to be married later this year.

A pal tells Us, "They are very happy." It's the first child for the singer; Beatz, 31, is father to sons Kaseem Jr. and Prince, both from prior relationships.

And Keys' husband-to-be is equally smitten. "What we have is so precious," Beatz gushed to the New York Daily News last year.

Of motherhood, Keys recently admitted, "I absolutely am very interested in starting a family. It is one of the most beautiful experiences to have in this life and I am looking forward to it when it is my time."
