Beyoncé Knowles has apparently enforced a party ban on Jay Z.

The A-list couple are currently involved in a media storm, after footage showing Beyoncé's younger sister Solange attacking Jay in an elevator was leaked.

The aftermath of the video has seen Jay accused of cheating on his wife of six years, all of which Jay's denied. In a move to prevent any more embarrassing mishaps, Beyoncé has reportedly told Jay to quit his partying ways, including nights out at his own New York club 40/40.

"The infamous lift video is something Bey would rather forget. To get her own back for all the rumours, which Jay has denied, she's making sure he avoids situations that could cause similar embarrassment," a source told British magazine Now.

The pair decided to give Kim Kardashian and Kanye West's lavish Florence wedding a miss last month, and apart from a statement they released saying they had moved on from the incident, have remained silent on the matter.

"Bey hit an all-time low after all the drama. She's so torn right now - she adores her sister just as she does her husband. Jay wants things to work so he's agreed to her plan. It's a tough time for them, but they're both determined to ride out the storm," the source added.

Prior to the Solange attack, Jay and Beyoncé were thought of as the picture of married bliss.

They're proud parents to daughter Blue Ivy, two, and friends say the power couple aren't ready to throw in the towel just yet. Jay's even willing to surrender his privacy to please his wife.

"Jay's still head over heels in love with Beyoncé. He doesn't care if she takes a peek at his phone from time to time," the insider added.
