It seems like Beyoncé had a enough of her hubby Jay Z's party days. Music-News.com reports that Beyonce Knowles has apparently enforced a party ban on Jay Z. This comes after footage showing Beyonce'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.
