Mya Weighs In On Jay Z, Beyonce Cheating Rumors: Singer Says, "Never Did, Never Was, Never Will" Denying That She Is Jay Z Mistress

Mya's "body is like whoa," but this singer is not having a "case of the ex," with Queen Bey's husband, Jay Z.

Mya is denying cheating rumors that have been spreading around like wildfire that she is Jay Z's mistress after Beyonce, performing her 2006 song "Resentment" in concert last weekend, apparently hinted that her hubby had cheated on her.  The song speaks about infidelity, and Beyonce added new lyrics, including the number of years she and Jay had been together, onstage in Cincinnati for the Part II: On The Run Tour.

MStars News recently reported that Twitter and Instagram were on fire, as Mya spoke out about the alleged long-term affair with the rapper.

The 34-year-old added more, responding to outrageous questions received from social media followers. Mya wrote on Instagram, "Never did, never was, never will. Illegitimate, thirsty sources with no facts and that's the 'media' for you-especially today. I play second to no one, pay my own bills, have my own label, own management company, rely on God only and respect myself & marriage too much for nonsense."

She continued: "False rumors are crafted for ratings & numbers. And miserable, unhappy people need someone to judge to deter the attention away from their own misery and feel better about their miserable lives. If they did it to Jesus, they'll do it to anyone. God bless."

The rumors of the suuperstar rapper cheating on his megastar singer wife began when urban site MediaTakeOut.com ran a blind item, about an online post claiming Jay Z had a longtime relationship with a "very short named R&B singer who hasn't had a hit in awhile and doesn't really even act or record any longer....She basically lives off the generosity of Jay-Z and a couple of other guys."
