(AllHipHop News) Rap star Lil Wayne wrote a letter to his fans today (August 16th), posted on his official website WeezyThanxYou.com. Lil Wayne is being held on Rikers Island, where he is almost finished a year-long sentence for attempted criminal possession of a weapon. According to the rapper, he has learned a number of lessons while being incarcerated and has vowed to not return to prison. “There’s some pretty cool people in here. Even though this isn’t a cool place to be,” Lil Wayne wrote in his fifth letter to fans. “I’ve learned plenty already and the best lesson is to not come back,” the rapper wrote. Lil Wayne revealed that he was put on a few extra pounds in muscle since being incorporated and that he appearance should be visibly different. “Now don’t be expecting me to look like Hercules when I get out, but I should be a little bulky,” Lil Wayne stated. The New Orleans rapper has managed to maintain a high profile since being locked away on Rikers Island in March, for having a loaded .40 caliber handgun was found on his tour bus and linked to him through DNA evidence. Lil Wayne has less than three months to serve before he is released from Rikers Island.Last week, the rapper called into Hot 97 and conducted an interview with Funkmaster Flex and later that same evening, “Right Above It” featuring Drake debuted on Power 105.1. “Right Above It” is the first release from Lil Wayne’s upcoming album I’m Not a Human Being, which is due in stores on September 27th.
