Whitney Houston's daughter Bobbi Kristina is reportedly under investigation for underage gambling.

The 19-year-old was caught on video playing a slot machine at the MGM Resort and Casino in Las Vegas on Saturday while hanging out with her 22-year-old boyfriend Nick Gordon. You have to be 21 to gamble in Vegas.

Bobbi Kristina was in town to accept the Millennium Award on her mother's behalf at the Billboard Music Awards Sunday.

The MGM and the Nevada Gaming Commission have launched investigations into the footage.

Underage gambling is a misdemeanor in Nevada, punishable by up to six months in county jail or $1,000 fine.
