Mgm Grand bosses in Las Vegas have launched an internal investigation following allegations Whitney Houston's daughter Bobbi Kristina Brown was caught gambling at the casino after the Billboard Music Awards on Sunday (20May12)
Video footage obtained by Tmz.com appears to show the teenager hitting the slot machines with her boyfriend - even though, at 19, she's too young to gamble in Sin City.
The website posted the video online on Monday morning (21May12) - hours after Bobbi Kristina had accepted her late mother's Millennium Award at the Mgm Grand Garden Arena.
Tmz.com reports officials at the Nevada Gaming Commission have also launched their own investigation into the footage.
Underage gambling is a misdemeanour in Nevada, punishable by up to six months in jail or a $1,000 (£625) fine.
