The pair clashed a number of times in the CBB house on Channel 5 earlier this summer, and it seems Heavy D is still after a fight.
In the house Big Brother was at one point forced to split the pair up after things almost got physical in one row.
Now Heavy D has challenged TOWIE's Lewis to a duel in a 'rap' video posted online.
In the clip, Heavy D also takes aim at Marnie Simpson, who appeared in the house with the pair and is now dating Lewis.
"Lewis is a **** and his bird's a ho," sings Heavy.
He calls for Lewis to face him in a charity boxing match.
Heavy said (via List): "Lewis mate, what you waiting for? Let's get it on in the ring.
"We've got the venue, promoters... what are you waiting for, big b******s?
"You can't do it when you don't have security or cameras around, can you?"
Will Lewis take on Heavy D's challenge?
