Introducing our new favorite rap duo, Rebellen!

Rebel Wilson stopped by Ellen DeGeneres' talk show today to debut the twosome's brand new rap jam, "Watching Cats on the Internet" -- and it's as amazing as it sounds.

Clad in matching track suits, the two hilarious women spit some serious rhymes about feline Internet videos, all while meow-ing and clawing their way through cat-like choreography.

The talk show host says the single is their first cut from their debut album, "White Ladies Rapping" ... something we really wish was real.

With "Pitch Perfect 2" on the horizon, maybe DeGeneres can make a cameo in the high-anticipated flick. We'd love to see them collaborate again!

Check out the ridiculous performance above.
