A rapper named Liv, who alleges to be a former mistress of Jay Z's, released a song dissing Hova's wife Beyoncé. The track, titled "I'm Sorry Mrs. Carter," which is laid over Outkast's "Ms. Jackson" beat, attacks the "Drunk in Love" singer.

The lyrics of the song portray Liv as a victim of Beyoncé's jealousy after Jay Z hit on her. However, she denied having a romantic relationship with the "Empire State of Mind" singer but had a connection over the music.

"Me and Jay never screwed," Liv rapped. "We connected on some hip hop s***, he could be himself with me any day that s***. We were attracted like magnets, us crossing paths was no accident. When I stepped out, I took a piece of his heart."

In "I'm Sorry Mrs. Carter," Liv went on to say the rapper "likes all natural, flawless model chicks like her."

Liv made similar claims last year about Jay Z, saying he made advances on her just before the couple married in 2008. She also named other people the rapper has allegedly cheated with on the track, including Rita Ora, who has denied these rumblings.

The husband and wife have been performing together for the past several weeks on their "On the Run" tour. This first joint tour between the pair is set to make more than $100 million dollars and reach almost 1 million people, according to Live Nation.

While the duo have been more public together than ever before, rumors are running rampant that there is trouble within their marriage. After the now infamous elevator fight in May between Jay Z and Beyoncé's younger sister Solange, entertainment news is full of stories claiming that Jay and Bey are headed for splitsville.

"The clip, both shocking and embarrassing, opened the proverbial floodgates for gossip-mongers (and detractors) with speculation running rampant over the catalyst for the dust-up," Gerrick Kennedy, writer for the LA Times, wrote. "Despite releasing a statement assuring the public that the trio 'worked through it' and 'moved forward as a united family,' the public hasn't. A couple as image-savvy as Beyoncé and Jay Z certainly know that."
