Now that Lil Wayne's teeth are in order, the superstar MC is expected once again to turn himself in to authorities, this time on Tuesday, to finally begin his one-year prison sentence stemming from a 2007 arrest on gun charges.

The rapper will be formally sentenced in a Manhattan courtroom by Judge Charles H. Solomon after last month's postponement due to Wayne's dental surgery. Wayne is scheduled to enter his plea, and authorities will then whisk him away for processing at New York's Rikers Island.

There, Weezy's world will be unlike anything he's experienced before in his life.

According to a prison guard who spoke with MTV News, the Cash Money lyricist's hectic life of recording, touring and performing will be replaced by a regimented routine that features wakeup calls at 4 a.m. and dinner at 3 p.m. The guard, who declined to be identified because of the sensitive nature of the information, said Wayne should be treated like a regular inmate for the most part, obvious safety concerns aside.

"He'll be housed with inmates who are classified in his category, and he'll be able to be a regular inmate," the guard said. "He'll be able to watch television, go into the day room and congregate with people of his classification."

Wayne's classification, however, will most likely be decided based in part on his fame, the guard said. The guard also suggested Wayne would be placed in the Eric M. Taylor Center at Rikers, on the north side of the facility in East Elmhurst, New York.

"It's a high-class area where he will be segregated from [the general] population," the guard explained.

The rapper, though, won't be in a dormitory setting, as a retired corrections officer told MTV News last month. He'll likely have his own 10-by-15-foot cell with a toilet, sink, bed and one window. "He'll be able to see another wall [outside the window]," the guard said.

Wayne also will not be able to make many of his own decisions during his incarceration, including what recreation he participates in and the option to work. "He probably won't be assigned a job, just to keep things quiet," the guard said, alluding to the rapper's safety and the overall safety of the unit he's placed in.

When Wayne graced the cover of Rolling Stone recently, he said he would bring an iPod loaded with music he could write to; the guard, however, emphasized that an mp3 player would be classified as contraband, meaning the rapper would not be permitted to have one.

Weezy will have plenty of downtime, though, of which he can choose how he passes the time. In between the rapper's 4 a.m. wakeup calls for breakfast, 11 a.m. lunchtimes, 3 p.m. dinners and evening lights out, he has a number of options. He's allowed to receive two visits per week, which can be any day of the week or weekends at various times.

With his commissary money, he can purchase a transistor radio. It's unlikely that he'll visit the law library, as he has no appeal to make for his case; he's widely expected to be released after eight months if he serves with good behavior. If he wishes to participate in religious activity, he can be excused to visit the places of worship within the prison.

Throughout Wayne's sentence, he'll have an intermittent amount of time to interact with fellow inmates. According to the guard, that decision is one that is made by the governing officers of the facility to keep things orderly. For the most part, Wayne will be isolated and treated like any other numbered prisoner at Rikers Island.

"He'll have no preferable treatment at all. He'll be treated like a regular inmate," the guard said, with one added caveat: "He may have heightened security. A guard will walk with him when he moves from location to location."
