JAY-Z POSSE REFUSES TO PAY BAR TAB?: Record execs reportedly wine and dine rapper, then skip out on $1,500 bill.

       *A couple of record company big-whigs are being accused of skipping out on a pricey bar tab that included drinks bought for rapper Jay-Z.      

       According to the New York Post, Atlantic Records executive Michael Kyser and Universal Music Group honcho Shawn Costner took Jay-Z and his entourage out to M2 in Chelsea in February and racked up a $1,500 tab.      

       "Jay-Z ordered a bottle of Patron Platinum and some expensive champagne, and everything was going great," M2 manager Dan Develin tells Page Six. "The waitress has known him for five years, and he's a good friend of [owner Joey Morrisey], so we ended up comping a lot of their bill."       

       But when the check came for $1,500 -- amounting - amounting to less than a third of the tab they'd actually rung up -- things got hairy.     

       "Kyser and Costner were making a big show of wanting to take Jay-Z out, so they started arguing over who got to pick up the check," Develin says. "Jay-Z ended up tipping the waitress $500 and going outside to wait."       

       Eventually, Develin says, the two decided to split it. After Costner's corporate MasterCard was declined, however, Kyser agreed to foot the entire bill.       

       "Before we could get him to sign the receipt, he left the club," Develin says. "Of course, we still have his card, so we called up his office, and his assistant told us someone would come by to sign. Weeks went by, and no one ever did. Finally, we got a call from AmEx and were told that Kyser was disputing the charge. When we called him up again, his assistant said, 'Oh, Michael says he doesn't actually remember being there' -- which is crazy because we have his card and photos of him and Jay-Z."       

       Owner Morrissey said, "We just want to settle this and be done without having to press charges."
