Jay Z's mistress or the person alleged to be the root cause behind the strain in the romantic relationship between the rapper and diva wife Beyoncé Knowles, is now ready to come out in the open and even put up a fight against Queen Bey.

Rapper and model Liv, who is currently being linked to Beyoncé's hubby, has dropped a subtle diss music video titled "Sorry Mrs. Carter" against the real and legal Mrs. Carter on Monday.

From the title of the video alone, most if not all can easily derive that Liv is throwing shade against the "Single Ladies" hit maker, TV Guide noted.

Of course, it's pretty obvious that Carter is the real surname of Jay Z, and this alone would tell that Liv is indeed trying to make a statement against Beyoncé.

The lyrics of the song also stir more controversy because Liv maintains that though she was never romantically or sexually involved with Jay Z - so is she not Jay Z's mistress all along? - the "Run This Town" rapper has always had that desire to "screw" her despite being legally attached to Solange Knowles' sister.

"Sorry Mrs. Carter" may sound very familiar since it's heavily based from OutKast's "Sorry Mrs. Jackson."

The following are some parts of the track that could really enlighten one that indeed Liv is throwing shade at Mrs. Carter.

"You know what I was gonna respect you but since you crossed over into my lane it's time to check you. The man? He likes model chicks. He like all naturally flawless model chicks, like me."

"Girls can't run the world fightin' over me, all my single ladies better keep in mind when them those tables turn you gon' be the wife. Why don't you tell these girls how to be wives? Why don't you tell these girls how to act around yo; husband?"

Meanwhile, Liv also took to Twitter to share a cover art for her new single and she also used it as her new profile photo. The snap shows Jay Z's alleged mistress sporting skimpy bikini, and she captioned it, "Getting ready to drop #SorryMrsCarter #YesLIVCan

A couple of hours later, she followed it up with: "#SorryMrsCarter just dropped... link in my bio... #YesLIVCan #YLCStudios."

Jayz Z's alleged mistress is yet to personally confirm whether her new music video is indeed intended against Beyoncé.

On the other hand, several sources previously said that because of the rapper, Jay Z and Beyoncé are officially divorcing following their "On the Run" tour next month.
