Jon Bon Jovi opened up to London's Evening Standard about Richie's highly publicized departure from the band back in early April. It was previously reported that Richie left over financial differences, but Jon's statement hints towards something else. It's no secret Richie entered rehab in 2011 for alcohol abuse. Then the singer turned his attention towards Justin Bieber and had some choice words for him, too! Jon was less than thrilled when he learned The Biebs showed up almost two hours late for a London concert. Take a look and see what he had to say!.
