Jay Z is not cheating on Beyonce with Mya. She denied having an affair with Queen Bey's husband. Mya took to Instagram and cleared that she was not Jay Z's item.

"Heard you and Jay Z had an 11-year affair. Are you his side chick or nah?" wrote a fan.

Singer Mya debunked all the reports that she had an affair with Jay Z by posting a message on her Instagram page.

She responded to the fan's query.

"Never did, never was, never will. Illegitimate, thirsty sources with no facts and that's the "media" for you-especially today," answered Mya.

"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 way too much for nonsense. 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."

According to Daily Mail, reports surfaced earlier this week that mentioned Jay Z was having an affair with a "short named" R&B singer.

Mya's disagreement appears in the midst of Jay Z and Beyonce's controversial show on Saturday during the "On The Run" tour.

Reportedly, Beyonce changed the lyrics of "Resentment" which defines the emotions of a woman who has been cheated on.

"Been ridin' with you for twelve years. Why did I deserve to be treated this way by you? (sic)."

The original lyrics goes like this - "Been ridin' with you for six years. Why did I deserve to be treated this way by you? (sic)."

"Like I couldn't do it for you like your mistress could" was changed by Queen Bey to "Like I couldn't do it for you like that wack b**ch could (sic)."
