Grammy-winning R&B singer Alicia Keys, 29, has married her long time boyfriend, rapper and record producer Swizz Beatz, Us Weekly magazine reported on Sunday.

Keys, who is pregnant with her first child, and Beatz exchanged vows in a small ceremony in a private home on the Mediterranean Sea, the celebrity magazine reported.

The magazine's web site had a picture of the couple, showing Keys wearing a cream Grecian-style dress and Beatz wearing a tuxedo.

The couple has been together since 2008.

Keys has won 12 Grammy awards since releasing her first album "Songs In A Minor" in 2001. She released her fourth studio album, "The Element of Freedom", last year.

Beatz, whose real name is Kasseem Dean, is working on his third album.
