Alicia pregnant and engaged

Baby joy ... Alicia Keys and Swizz Beatz

R&B star ALICIA KEYS is pregnant with her first child.

The singer - who teamed up with JAY-Z on his hit single Empire State Of Mind - has also announced she's engaged to music producer SWIZZ BEATZ.

A rep for the couple said: "They are very happy.

"Alicia is with the man who has inspired so much of her music and her album The Element of Freedom."

Swizz - who has two sons from previous relationships - popped the question in January.

The happy news follows the pair's appearance at Alicia's Keep A Child Alive ball in London last night.

The 29-year-old recently admitted she'd love to start a family.

She said: "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."

Congrats to you both.
