TMZ reports that "guitarist 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."
Apparently, "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 them, 'It's a classic Jagger/Richards blowup.'
Their sources go on to say part of the problem is that Jon constantly belittles Richie. But there's another part of the problem - they're fighting over money."

Bon Jovi's next show is tomorrow, April 5th in Winnipeg, MB; guitarist Phil X is filling in for Sambora. The current leg of the tour is scheduled to end April 25th in San Jose, CA. Bon Jovi's complete live itinerary can be found here
