Alicia Keys: cheated on by hubby Swizz Beatz?

Both present at Fashion Week this weekend, the couple seemed very happy but it apparently a cloud has come to ruin their paradise.

According to Perez Hilton, Swizz Beatz is rumored to have sent salacious messages to a 23-year-old woman named Christina Elizabeth.

Beatz and Elizabeth met at a 2007 birthday part for Solange Knowles. Since that meeting they are rumored to have kept in touch.

Alicia Keys has been married to Music producer Swizz Beatz since last summer and the couple has a son, Egypt Daoud Ibarr Dean, born in January.

Swizz Beatz is already the father of 3 children with three different women.
