A rep for MGM Resorts International tells TMZ, Bruno Mars doesn’t have a $50 million gambling tab on the books with them — even though some recently alleged the opposite. Instead, MGM came to Bruno’s defense calling the allegation he owes a massive sum completely false. In fact, the Las Vegas hot spot is super excited to collaborate with the Grammy winner again in the future — not exactly the tone someone would take with a dude who’s got a fat bill. This update comes shortly after a report began circulating this past week that claimed MGM basically owned Bruno over an alleged gambling bill that was worth tens of millions. While Bruno has yet to address the gossip, MGM made it clear that there is nothing shady about their business relationship. BTW, Bruno’s got an upcoming residency there at the resort.
