Mötley Crüe guitarist Mick Mars now has a Just Sayin account, the app site for Twitter that allows you to leave voice messages for others. Mick and bassist Nikki Sixx have been going back and forth all evening, busting on each other. On one voice message, Nikki told Mick that he was going to “kick his ass,” but not break his fingers. If you want to leave a message for the legendary guitarist, go here. Mick’s handle is @mrmickmars.
