Hip-hop star Alicia Keys, who broke out years ago with her hit 'Fallin', might be a home wrecker after she was spotted canoodling with a married man.

Alicia Keys, best known for her vocals and pianist abilities, might have caused super-producer Swizz Beatz to leave his wife - but Swizz is saying the singer has nothing to do with it.

Our friends at TMZ break it down: We've seen Swizz and Alicia out all over the place getting real cozy, but Alicia insists to US Weekly she's not "in any way linked" to his decision to separate. Swizz claims estranged wife Mashonda is trying to smear Alicia. The ex-couple also have some cash issues -- there's a lien out for $800K in back taxes.

So what do you think? Has Alicia been getting too friendly with the married producer?
