Guns n' Roses front man Axl Rose's career is littered with juvenile feuds, from dust ups with Kurt Cobain and Scott Weiland to spats with his own bandmates and assorted hotel staff, like the Swedish security guard whom he allegedly bit during a drunken brawl in 2006. One of his longest running rivalries is with Motley Crue's Vince Neil. In 1989, Neil punched out GnR guitarist Izzy Stradlin in retaliation to an earlier fight, provoking a string of insults and threats from Rose. Things eventually simmered down but Neil has rekindled the flames in recent years. For example, in 2008 he chided Rose in the UK press after GnR's long-awaited "Chinese Democracy" bombed.

"A buddy of mine went to go play guitar for him. They rehearsed for three months and Axl never once turned up. Rule number one: show up!" he told "The Sun" newspaper. "He's been doing that for many years. Finally I think the fans just went, F*** it - can't do this anymore...You can't be a fan when you can't see the band."
