2 Chainz basically already confirmed the news that he has signed with Def Jam, but the rapper formerly known as Tity Boi paid a visit to MTV's RapFix Live to make the official announcement. While he was there, he also dropped the news that he and Kanye West have been collaborating and that they already have some music ready to go. He told Sway:

"One thing that people might not know, is that I've been working with Kanye West for the past year. We have records together. We have ideas that we plan on releasing to the world real soon."
