As if following a script for teenage rebellion, 17-year-old 'Hannah Montana' star Miley Cyrus is simply not going to stop at flaunting sexy stage fashions, grinding on a dance floor with pals after hours and releasing an eyebrow-raising new music video featuring blindfolds and bedsheets.

She also has no problem hitting a bar and kicking back like the big kids do.

Cyrus was spotted in Madrid this week casually drinking what appeared to be a Corona while out on the town with friends. The legal drinking age in Spain is 18, however authorities are reportedly lax about enforcing the law, and many allege that underage teens commonly drink without consequences.

But now, according to TMZ, the International Institute for Alcohol Awareness says the former Disney darling has gone too far.

James Copple, who heads up the organization, explains, "The young people that see her as a role model could mimic the same behavior, and as a consequence, will go out and become intoxicated, putting their safety at risk."
