Maybe T.I. can look to Lil Wayne for advice on how to stay out of the pen, because it appears Lil Wayne is serious about his government-mandated sobriety.

TMZ reports that Wayne, who is banned from consuming alcohol until 2013, has instituted a zero-tolerance no-alcohol policy backstage and on his tour bus.

A rep for Weezy's "I Am Still Music Tour" says that the concerts have "a dry backstage as we are committed to keeping a safe and professional atmosphere to ensure a smoothly running tour."

"There is no ban on alcohol served at the venue," added the rep.

Wayne was sentenced last November to a three-year probation that prevents him from using drugs or alcohol, in addition to associating knowingly with any person engaged in criminal activities.
