Jon Bon Jovi is not a Belieber. 
 
 The legendary Bon Jovi front man is slamming 19-year-old pop star Justin Bieber for his truly unprofessional antics of showing up two hours late for his show at the O2 arena in London in March 2013 – and RadarOnline.com has the details. 
 
 “Every generation has guys that do that, none of that is new,” the 51-year-old spat to the Standard while on tour in Vienna.

 “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.” 
 
 The rocker, who has been in the limelight since releasing the 1984 hit album Bon Jovi, continued to rant about the teenager’s less than professional demeanor. 
 
 “Do it once, you can be forgiven. Do it enough times and shame on you. They won’t have you back,” he said. “Then it just becomes a cliché. It’s really not cool — you’re an a**hole. Go to f**kin’ work!”

 Back in March, Bieber defended his tardiness claiming that he was only 40 minutes late to the show and that it was only because of technical issues. 
 
 On Sunday night, Bieber showed up to the Billboard Music Awards, where he was booed when he went up on stage to accept the New Milestone Award. ||||| Justin Bieber Talk About My Parties I'll Sue You for $5 Mil

– If you aspire to attend a party at Justin Bieber's house, first you'll have to score an invitation ... and then you'll have to sign a Liability Waiver and Release. TMZ got a copy of the fairly insane document, which says that if you tweet, blog, text message, or otherwise talk about the party in any way, shape, or form, you owe the Biebs $5 million. Not only can you not discuss the party; you're also not allowed to discuss the other guests' health or philosophical and/or spiritual views. Yep, it specifically says that. By signing the form, you also acknowledge that some of the party activities are "potentially hazardous and you should not participate unless you are medically able and properly trained," because you risk "minor injuries to catastrophic injuries, including death." (Oh, and you agree not to sue Bieber, should you be catastrophically injured during a crazy game of beer pong.) TMZ notes that other stars make partygoers sign similar waivers, but notes that Bieber's is nonetheless "hilarious." (Click to find out which fellow singer thinks Bieber is an "a--hole.")
