The Wanted have made waves in America, with a number three single and nominations for the Teen Choice Awards and VMAs, and now the boys appear to be more relaxed about their gigs by drinking on stage.
The five piece were in Las Vegas - maybe the city of sin got to them?
The band hit the booze hard in New York on Friday night (October 19) and then travelled to Las Vegas to perform in the Mirage Hotel.
It seemed they were not done with their partying ways as the boys juggled their mics with bottles of beer.

Noticeably absent was Siva Kaneswaran, who tweeted an apology for his absence, citing personal reasons.
He tweeted: "Gutted I missed the gig in Vegas! Boys having a blast without me! Just had something private to attend to. Thanks for the tweets home safe x".
No word yet whether the boys bought a round for the concert goers!
