Watch Big Sean & E-40 perform "I Don't Fuck With You" live on Jimmy Fallon.
Backed by The Roots, Sean & 40 threw on their winter gear and performed together for the very first time ever. The track, which is available on iTunes, will see life on Sean's upcoming solo album, which he says is "pretty much ready". Look for that to drop in early 2015.
