[UPDATE BELOW] Today rapper Lil Wayne is expected to go to Rikers Island, where he'll spend most of 2010 behind bars after pleading guilty to "attempted" gun possession charges. In a cover story interview with Rolling Stone, Wayne says he hasn't sought advice on how to get through Rikers, because "This is Lil Wayne going to jail. Nobody I can talk to can tell me what that’s like. I just say I’m looking forward to it." It can be a mellow place if one avoids the fight clubs. Wayne spent his last night of freedom in the studio recording tracks bound for "Tha Carter IV," and also send out this heartfelt message, or "shout out," for his fans:

I’m out this bitch. To all my fans, my real fans, I really, really, really truly love you. I love you with all of me, for real. I’ll probably be loving everything else because I love you so much. Thank you from the bottom [of my heart]. Do not forget about me ’cause I will forever think about you, and I cannot wait for you to see me again. I’m out.

It's going to be a long, dull year without Weezy, but his manager Cortez Bryant says he's exploring ways to keep Wayne in the public eye during his bid. A jailhouse Twitter account is in the works, and Wayne promises, "I’ll have an iPod, and I”ll make sure they keep sending me beats." "Tha Carter IV" is expected to drop when Wayne gets released.

UPDATE: Well, see, the thing is, this really isn't a convenient time for Lil Wayne to go to prison, because he's got a lot of work he needs done on his teeth! At his sentencing today, Wayne got a temporary reprieve in order to finish a string of recent surgeries for an unspecified dental problem before he goes to prison. Judging by these recent photos, we're guessing he's still got some de-icing to do—Wayne reportedly has $150K worth of diamonds on his teeth. The AP reports that his sentencing is now set for March 2, and a judge says it won't be put off further.
