Justin Bieber doesn't have a fan in Jon Bon Jovi.

The Jersey rocker slammed the pop star for being disrespectful to fans after showing up for shows late while in Europe.

Bon Jovi told London's Evening Standard,

“Every generation has guys that do that, none of that is new. 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!”

Back in March Bieber was over 2 hours late for a show at London's O2 Arena, later blaming it on 'techincal issues' and claiming he was only 40 minutes late.
