Bon Jovi calls Justin Bieber an 'a**hole'

Jon Bon Jovi has a reputation for being a nice guy, but he had some harsh words for Justin Bieber in a recent interview with The Evening Standard.

The long-time Bon Jovi frontman said Monday that the 19-year-old pop star was disrespectful to fans when he was two hours late to a concert at London's O2 Arena in March. While Bieber blamed his tardiness on "technical issues," Bon Jovi wasn't buying the excuse.

“Every generation has guys that do that, none of that is new," the 51-year-old rocker said in the interview.

"They run the risk of disrespecting their audience members who have worked hard to pay for their ticket, to give you the permission to take two or three hours of their lives -- or in that kid’s case, 80 minutes of their lives.

Do it once, you can be forgiven. Do it enough times and shame on you. They won’t have you back. Then it just becomes a cliché. It’s really not cool — you’re an a**hole. Go to f***in’ work!"
