Listen to Bon Jovi on iHeartRadio

Bon Jovi frontman Jon Bon Jovi is denying allegations that he kicked Richie Sambora out of the band. 

The singer tells the Austin's American-Statesman that Sambora is "doing all right," but admits he hasn't "spoken to him."  He adds that the guitarist walked away from Bon Jovi's tour on his own accord.  

Jon says the rest of the band was "surprised" last week when they got a call a few hours before their their April 2nd show in Calgary notifying them that Richie "wouldn't be there."  But he still isn't offering any details behind Sambora's departure, and simply adds that it's "a personal matter."  Reports have surfaced claiming that Jon - at his wife Dorothea's urging - kicked Richie off the tour over Richie's supposed substance abuse. 

Following the Calgary show last week Bon Jovi posted a website message stating that Sambora's absence was "due to personal issues," but the band would still continue with their tour as scheduled. 

The group has tapped guitarist Phil "Phil X" Xenidis to fill in for Sambora.  Bon Jovi will be performing in Austin Wednesday night.
