Casino regulators are investigating footage of Bobbi Kristina Brown, the daughter of the late Whitney Houston, allegedly gambling underage over the weekend while in Las Vegas, Nev. for the 2012 Billboard Music Awards.

A video of Brown gambling at the MGM Grand Resort and Casino was first posted by TMZ on Monday, showing surveillance footage of the 19-year-old playing a slot machine with 22-year-old boyfriend Nick Gordon on Saturday evening.

The video prompted regulators at the State Gaming Control Board to launch an investigation to determine whether or not Bobbi Kristina Brown was gambling, according to the Las Vegas Review-Journal, as it is illegal to gamble under the age of 21 in Nevada. Chairman Mark Lipparelli told the Review-Journal that officials will investigate the video as well as casino employees' knowledge of an underage gambler.

According to LVRJ, spokesperson Gordon Absher MGM Resorts International is cooperating in the investigation by the Gaming Control Board.

The owner of the casino could be given a fine if the allegations are true. The Las Vegas Review-Journal said underage gambling, a misdemeanor in Nevada, could lead to to six months in jail or a $1,000 fine.

TMZ reported Bobbi Kristina Brown was in Las Vegas to accept the Millenium Award at the Billboard Music Awards on behalf of her mother, Whitney Houston, who died in February of drowning and effects of atherosclerotic heart disease and cocaine use, according to the Los Angeles County coroner's office.
