The guys in Motley Crue have had their share of disagreements over the years, and it seems like they might be in the midst of another one.

One thing everyone in the band seems to agree on is that the Crue is headed for a farewell tour in the not-too-distant future. Singer Vince Neil has discussed their impending retirement repeatedly throughout the year, at one point chalking it up to this simply being the right time for the band to say goodbye. However, Neil's latest thoughts on the split seem to have ruffled a couple of feathers with some of his bandmates.

"Mick’s (Mars) health is not that good, and touring is tough on him," Neil told the Oakland Press during a recent intervew. "I’m sure in five, 10 years’ time we’ll probably do something together again, but it’s not gonna be like a Kiss farewell to the farewell to the farewell tour. We’re not gonna be like that."

Neil's remarks regarding Mars' health are in reference to his struggle with ankylosing spondylitis, a chronic condition that causes spinal joints to fuse together -- and while it's certainly painful, Mars insists Neil doesn't know what he's talking about. "Any rumours regarding a farewell tour due to ‘my poor health’ are BS," he subsequently tweeted. "I am doing fine. My AS has never kept me from touring and never will."

Following Mars' social media retort, Nikki Sixx -- who has already cautioned fans not to "freak out" about the retirement -- added his own two cents to the Twitter fray, tweeting, "Don't get ya panties in a wad so fast, we haven't booked our farewell tour. It's like some people can't wait to get rid of us."
