The former bassist and personal assistant for Motley Crue frontman Vince Neil is threatening to sue the singer over tax issues.

Alan Vine, who played bass for Neil's solo band about a decade ago, claims that Neil's business manager screwed him and reported inflated earnings. That has caused him to have issues with the IRS.

Vine went public with the charges in a lengthy open letter posted on Metal Sludge where he admits that Neil probably doesn't know the extent of the issue, but he's tired of getting blown off by the singer's handlers.
