Miley Cyrus Private Drinking Party

Miley Cyrus Private Drinking Party

With her parents in the middle of a divorce, underage Disney pop princess Miley Cyrus, 17, threw back a Corona cerveza at a club in Madrid, Spain last night ... where the legal drinking age is technically 18 -- but there's a catch.

Miley Cyrus was caught unaware by the paparazzi as enjoyed while having a drink at a Corona cerveza at a club in Madrid, Spain, last night, November 5.

There’s also an uproar over Miley drinking as the legal age of drinking in that country is 18 and she is just 17 right now.

However as reported,”Several Spanish authorities contacted, who each confirmed the law … and then made it clear that underage drinking is simply no big deal in their country.”

One police officer told us ... people as young as 16 are cool to consume "certain" beverages in Madrid -- but the cop refused to explain what those beverages are.

Well that’s nice for Miley…
