Bon Jovi called Justin Bieber out! He has a huge problem with artists being late to their performances, like Justin was back in London a few months ago.

Justin was at least 40 minutes late to his show in London and blamed it on "technical issues". 

Bon Jovi tells the London Evening Standard that "Every generation has guys that do that. None of that is new."

He also says, "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."
