Alicia Not Keys to Swizz Split

Super-producer Swizz Beatz is splitting with his wife -- but it's not Alicia Keys' fault. So he says.

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.
