Caught on tape?

TMZ posted a video Monday allegedly showing Bobbi Kristina Brown, the 19-year-old daughter of the late Whitney Houston and ex-husband Bobby Brown, gambling in a Las Vegas casino over the weekend. Now, the hotel casino and Nevada Gaming Commission are investigating the footage.

In the video, Bobbi is seen allegedly playing a slot machine Saturday at the MGM Grand with her adopted brother and rumored boyfriend, Nick Gordon, 22. In Nevada, a gambler must be 21 or older. Underage gambling is a misdemeanor and violators are subject to 6 months in jail or $1,000 fine.

Gaming Control Board Chairman Mark Lipparelli told the Las Vegas Review-Journal Monday that they are looking into the matter and whether casino employees allowed the Bobbi Kristina to gamble. MGM Resorts spokesman Gordon Absher said the casino "will cooperate fully with the Gaming Control Board."

Bobbi was in Las Vegas to attend the Billboard Music Awards at the MGM Grand Garden Sunday. She helped introduce a special tribute to her mother, Whitney Houston, who died Feb. 11 at the age of 48.

While accepting the Millennium Award on Houston's behalf, a visibly emotional Bobbi said, "I just want to say thank you to everyone who's supported us through it all. Not just from when it was good, but when it was bad, too. Just everything."
