An Ohio man is accused of stabbing a close friend because the victim did not know Beyonce and Jay-Z are married.

Ronnie Deaver, 31, had close friend Mark Kozelka, 48, over at his apartment in Garfield Heights, Ohio, to watch videos. “An argument erupted when it was realized that the victim did not know who singer Beyonce’s husband was,” Detective Marty Compton of Parma Police Department said.

“Both males then faced off during the argument and the victim was stabbed in his left side. The victim was subsequently transported to the hospital where he underwent surgery. He is currently in stable condition and remains hospitalized for what appears to be a non-life threatening injury.”

A woman in the house, Jennifer Fornari, 31, was also arrested for obstructing justice and tampering with evidence after she allegedly lied to police that Deaver no longer lived there so he could escape out of the rear window.
