The co-hosts of the brand new Channel 5 show tackle everything from Adele to Outkast as they battle it out and do their best impressions of much-loved songs.
However, our favourite moment has to be when Pro Green decides to take on a bit of Spice Girls!
And, Scary Spice Mel was rather impressed, as she said: "Good choice!"
Lip Sync Battle, which airs on Spike in America, is already a huge hit in the States. The show focuses on two well-known celebrities going head-to-head with show stopping routines and smash hit songs, all in front of a studio audience.
Channel 5's Commissioning Editor, Entertainment Steve Regan said: "We couldn't be more excited to announce Pro Green as Mel's co-host, they're a match made in Lip Sync Heaven.
"Take Mel B's edgy attitude and Professor Green's urban cool, throw in incredible performances from well known faces and we're expecting fireworks!"
Lip Sync Battle UK starts Friday 8 January at 10pm on Channel 5.
