The Knowles Sisters @ the opening of Jay-Z's 40/40 Club

The Knowles Sisters graces the red carpet with their usual sexy and stylish aura. Beyonce's love Jay-Z is very glad for the successful opening of his 24,000-square-foot sports bar and lounge, 40/40 Club at The Palazzo Resort-Hotel-Casino.

Jay-Z told the crowd: “I just want everyone to have a good time and not get caught up in the whole glitzy pretentious clubbing thing. But I’m up for a big night, and a big year next year. Good things are gonna happen.”

“The 40/40 Club, named after one of sport’s most prestigious achievements - 40 home runs and 40 stolen bases in the same season, combines a multi-level ultra sports bar with a chic lounge all under the direction of hip-hop mogul Jay-Z.” The sports memorabilia amidst the lavish gold and platinum decor will serve as the perfect backdrop for the ultra luxurious sports bar.”
