Alicia Keys debuted a slight baby bump Monday in Paris.

Walking hand-in-hand with fiance Swizz Beatz, she was all smiles as she left her concert at the Palais Omnisports de Paris.

On Thursday, the singer, 29, announced to UsMagazine.com she was expecting her first child. She also confirmed Us' original report that she's engaged.

"They’re very happy," says a friend of the duo, who’ve been together since fall 2008 and plan to wed later this year.

Beatz, 31, a producer, has two sons, Kasseem Jr., 3, and Prince ­Nasir, 9, from previous relationships.
