Nikki Sixx

This may wind up being the most unexpected Twitter feud of 2012: Motley Crue bassist Nikki Sixx vs. Kirk Cameron, a.k.a. Mike Seaver from the '80s television show 'Growing Pains.' Sixx is one of a growing number of celebrities speaking out against Cameron's recent anti-gay marriage comments on 'Piers Morgan Tonight.'

In the wake of Whitney Houston's untimely death, some of her fellow pop stars are coming out of the woodwork to discuss their own struggles with addiction, as well as the way the entertainment business can help enable patterns of destructive behavior. Motley Crue's Nikki Sixx added his two cents via an appearance last night (Feb. 15) on 'Piers Morgan Tonight.'

It's been a few months since we've been treated to a flareup in the ongoing war of words between Motley Crue and Godsmack, but just when we were starting to worry that we'd have to sate our appetite for rocker feuds with the Van Halen/Chickenfoot and Axl/Slash beefs, Motley's Nikki Sixx has made it clear that he still isn't a fan of Godsmack's Sully Erna.

Only yesterday, Vince Neil was telling the media that the Motley Crue's upcoming Vegas romp might be the start of their farewell. Now today, word comes in from bassist Nikki Sixx that, though a farewell may be in the cards at some point, it might be a long goodbye.
