Jon Bon Jovi's dispute with Denise Richards has hit a new low, according to reports.

Richards is dating Bon Jovi's bandmate Richie Sambora, and reports are now suggesting that the singer wants her banned from coming on tour with the band.

A spokesman for the musician has denied the claims, and seems adamant that they are "not true", but an inside source claims the situation has become almost unbearable for the band dynamic, and the guitarist's place in the group is consequently under threat.

Richards has been with Richie since her divorce from ex-husband Charlie Sheen.
