Lil Wayne already has a super successful franchise in [article id="1670314"]Tha Carter series[/article], so why would he want to rest on his laurels?

Young Money Records President Mack Maine exclusively revealed to MTV News that not only is Weezy about to lay down tracks for a sequel to his Rebirth rock album, but the "How to Love" hitmaker is already knee-deep in recording a follow-up to 2010's [article id="1648768"]I Am Not a Human Being[/article] LP.

"He's, like, 12 songs in, and he went crazy. He went left. He's in Martian land right now," Mack said of I Am Not a Human Being 2.

The original Human Being was released digitally in September 2010 while Birdman Jr. was in jail. Though Wayne wasn't around to promote it, the album contained singles like "Right Above" with Drake and "I'm Single" and has been certified gold by the RIAA. The [article id="1650416"]physical copy of the album debuted at #1[/article] when it dropped in October 2010.

According to the YM prez, each separate album franchise allows Wayne the chance to showcase different artistic sides. "He gets to show his rock side, he gets to show his gangsta side and talk to the women on one side," Mack said of the Rebirth and Carter series, respectively. "On I Am Not a Human Being, he is definitely showing some weirdo, left-brain, I'm-not-from-here type side. He can say what he wants. There are no boundaries, there are no limits."

However diverse he may be in the booth, when Wayne performs live, he is able to pool all his collective talents together -- as well as their respective fans. "He captures all those different audiences, and then at a concert or a show, you bring all those different people together," Mack explained. "You bring your Rebirth rock people, you bring your Carter people, and you bring your I Am Not a Human Being [crowd], and you have a great show. That's why we sell out arenas every night."

There is no release date yet for I Am Not a Human Being 2 or Rebirth 2.
