Jay Z's alleged mistress, rapper Liv, has now comes out with a controversial new rap song about her and Jay Z where she claims she never had any physical relationship with Beyonce's husband but the two had some emotional bonding. In the track titled "Sorry Mrs. Carter," Liv apologises to Beyonce first but then also disses her in other lyrics and tells Bey to be a good wife!

"F-k f-king to the top, me and Jay never screwed," Liv raps in the new song directly stating the fact that she never had sex with Jay Z.

"You got a good girl, why she messing with a bad guy?" Liv asks further in the song before finally addressing Beyonce as "Mrs. Carter."

"Sorry Mrs. Carter, this is for real. Why don't you tell these girls how to be wives? Why don't tell these girls how to act around yo' husband?," she disses Beyonce.

"The man? He likes model chicks. He likes all naturally flawless model chicks, like me. Jigga man, I don't care if you rap, you got to R-E-S-P-E-C-T," Liv raps further in the song referencing to Beyonce's song "Flawless."

"You got 99 problems, I'm not tryin' to be one. Girls can't run the world fightin' over men, all my single ladies better keep in mind when them those tables turn you gon' be the wife," she raps while keeping in mind Beyonce's single "Single Ladies."

"You out here tellin' them how to serfbort. Come on, now. Serfborts. Monica Lewinsky. You a married woman," the alleged mistress raps further as she uses the "Drunk in Love" catchphrase "serfborts."
