Pictures of Justin Bieber partying with friends at a Houston nightclub is prompting an investigation into possible underage drinking.
A rep for the Texas Alcoholic Beverage Commission tells TMZ.com a complaint has been filed, even though bar managers at NOX claim the 19-year-old singer was only drinking water.
Officials say the bar's license could be in jeopardy if investigators conclude otherwise.
Back in July a Chicago nightclub was slapped with a citation for allegedly serving the singer alcohol, though management at Bodi nightclub deny any laws were broken.
