Resigning from Def Jam doesn't worry Jay-Z but this one might.

The hip hop mogul's new Las Vegas club reportedly failed to pass a health and safety inspection leaving his New Year's Eve plans in disarray.

The boyfriend of R&B singer Beyonce Knowles was due to ring in the New Year at the latest branch of his upscale sports bar, The 40/40 Club, but the L.V. venue's opening will most probably be delayed after the surprising setback.

Celebrity blogger Perez Hilton cites a source as saying, "Unless Jay-Z and his team miraculously come up with certain licenses and certificates by Sunday, then they won't be ablt to go on with their New Year's Eve party plans."

And if that happens, then the rapper superstar will be forced to refund all tickets to the club's grand opening.
