Rapper 2 Chainz was everywhere in 2012. In the past year alone he appeared on 40 songs, which makes him quite different from other artists. So on the Dec. 17 episode of 'Jimmy Kimmel Live!,' 2 Chainz performed his latest single, 'I'm Different.'

The Atlanta rhyme-slinger had the audience waving their hands in the air and shaking their derrières to his piano-tickling jam. And much like his rap moniker, 2 Chainz came onstage wearing two looong gold chains and matching bracelets.

There's one more thing that's true -- his Grammy-nominated LP 'Based on a T.R.U. Story' has been certified gold for 500,000 copies shipped in the United States. "I wanna thank God, my fam, my team, fans, djs, taste makers, bloggers & u for your support!" 2 Chainz wrote on Twitter. Truuu!
