NEW ORLEANS — Pregnant R&B star Alicia Keys frightened fans on Saturday when she fell onstage at the Essence Music Festival in New Orleans.

The 29-year-old singer was performing "Love is Blind" when she stumbled and landed on her backside. Keys, who was hearing high heels, quickly recovered and took a seat at the piano to finish the song.

The Grammy winner's baby-to-be is reportedly fine after the fall.

Keys was one of the weekend headliners at the 16th annual event, sharing the bill with Janet Jackson and Mary J. Blige.

A rep for the singer confirmed in May that Keys was pregnant and expecting her first child with boyfriend Swizz Beatz. The twosome, who began dating in fall 2008, are also engaged to be married.
