Richie Sambora is bailing on the Bon Jovi world tour because of "personal issues," but it has NOTHING to do with substance abuse ... it's all about a war that's exploded between Jon and Richie.
Sources directly connected to Bon Jovi tell TMZ ... tensions between Jon and Richie have been running high for years and it's finally erupted. One source tells us, "It's a classic Jagger/Richards blowup."
Our sources say part of the problem is that Jon constantly belittles Richie. But there's another part of the problem -- they're fighting over money.
Richie was a no-show at a Bon Jovi concert in Calgary last night, and yesterday he posted on the Bon Jovi website that he was pulling out because of "personal issues."
During the Calgary concert, Jon told the crowd, "I had two choices: pack up and go home or give you everything I got ... Richie Sambora won't be performing for a while. If there's ever a night I need you, it's tonight, Calgary!"
In the meantime, Richie's been spending personal time with his daughter -- the two were on vacation in Hawaii last week. We're told it was an 11-day trip filled with zip-lining, hikes, paddle boarding, and chilling at the pool.
Richie has had alcohol issues in the past, but we're told in no uncertain terms ... Richie is clean now.
Sources close to the band tell TMZ ... Sambora's camp is hopeful the two sides can work things out before April 19, when Bon Jovi is set to play in L.A. -- Richie's hometown.
