Big Sean And E-40 Bring 'I Don't F--k With You' To 'Jimmy Fallon'

Some holiday cheer.

The holidays are about spending time with people that you love -- and letting those that you don't, know that you don't f--k with 'em. Right?

Well, either way, that's what Big Sean and E-40 did Tuesday night on "The Tonight Show Starring Jimmy Fallon," with a little help, of course, from the Roots. The track peaked at #1 on the Billboard R&B/Hip-Hop Songs chart, as well as the Rap Songs chart, and is the warm up for the G.O.O.D. Music MC's upcoming third solo album.

Later in the night, Sean then thanked the Jimmy and co. for having him on the show in an Instagram post.

The Detroit rapper's ex isn't the only thing he doesn't mess with. When MTV News recently sat down with Sean, we gave him some of 2014's biggest stories to find out if he f--ks with them or not. Check it out below.
