Madonna's daughter allegedly caught drinking at concert

Madonna's teenage daughter Lourdes was allegedly caught drinking booze at her mother's concert in Michigan on Thursday (01Oct15).

The 18 year old was photographed holding a can of Bud Light while partying in the front row at her mother's show in Detroit.

Lourdes attended the Rebel Heart Tour concert with a group of her friends and editors of TMZ.com have published photos of the teenager drinking from a can of beer during the concert.

The legal drinking age is 21 years old in the U.S.

Lourdes is a regular at Madonna's parties, and the teenager also attended her mum's lavish gypsy-themed birthday bash in August (15).

Madonna revealed earlier this year (15) that she does not scold her children for experimenting with various substances.

"I just ask my daughter to make wise decisions and to do things in moderation and to try not to mix her alcohol," she disclosed during an interview on Britain's The Jonathan Ross Show. "I am not going to say, 'No, don't do it' because that is just absurd. And it is not fair. Yeah, I did it."

Madonna's Rebel Heart Tour will travel to several more cities and the concert series is ending in Brisbane, Australia on March 27, 2016.
