Watch 2 Chainz Hilariously Perform Katy Perry’s ‘Firework’

2 Chainz's version will make you go 'oh, oh, oh.'

2 Chainz is best known as a rapper, but he's also a dope wedding singer.

Okay, so maybe that's not entirely true, but it is a reality in this sketch by Key & Peele that debuted on Buh Tuesday.

The clip features Chainz and Key & Peele's Absorption, a wedding band from Arizona that hilariously offers custom remakes of familiar tunes, from Macklemore & Ryan Lewis' "Same Love" to Beyoncé's "Single Ladies."

If you want 2 Chainz to join in on the fun, though, it'll cost you. "It's $75 every 30 minutes," "The Master Collaborator" said in the vid. "You do the math."

Pay his fee and you might get him to sing Katy Perry's "Firework" (as shown in the bit). But that isn't the only cut Chainz performs. He also does a mean "Don't You Worry Child" by Swedish House Mafia. Just check out the full clip below.
