Funnymen Mike Epps and Kevin Hart are getting serious about a war of words, and mutual pal Marlon Wayans is urging both comics to stop feuding.

Epps sparked the spat after criticising the Ride Along star during a radio interview on Friday (02May14), calling Hart "overrated".

Hart responded by taking to and posting, "Just heard @TheRealMikeEpps called me 'Overrated' on the radio this Am! I missed it bcuz (because) I was on set 'Working' do u remember what that is?"

The war of words continued throughout Friday, prompting Hart to Tweet, "Hey @TheRealMikeEpps why don't you do us all a favor and Kill your god damn self..."

He added, "Don't talk 2 me until u start selling out Arena's @TheRealMikeEpps if ur (your) shows aren't sellin & u need sum (some) help maybe I will send out a Tweet... Oh one more thing @TheRealMikeEpps if you keep talking crazy I will book shows the same day as you in the same cities and shut yo s**t down... Overrate That."

Marlon Wayans waded into the war or words, joking, "@KevinHart4real & @TheRealMikeEpps you boys stop it! Stop it now hear! Sound in' like 2 heathens!"

But Epps wasn't about to calm down. He had the last word, tweeting, "If it wasn't for the social media @KevinHart4real would not be present he was forced on you fans trough the web your gone (going) to realize."
