Rocker Jon Bon Jovi SLAMS Justin Bieber for his multiple concert delays.

In a recent interview with the London Evening Standard, the 51-year-old musician said that Justin was “disrespecting” his fans for showing up two hours late to a concert at the O2 arena – back in March.

He told the newspaper:

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 asshole. Go to f***in’ work!
