Lil Rel Howery is officially sick and tired of Katt Williams firing shots at him and insulting his craft.

You may recall during Katt’s infamous V-103 interview he talked about how ugly Rel was and totally disregarded his talent.

The comedian and actor took to Instagram Live to address Katt in a mature and respectable way.

But, at some point, Rel’s inner Chicago bubbled to the surface and he went all the way IN and told the Emmy Award-winning pint-sized comedian to “GROW THE F–K UP!

Rel, who stars in his very own Fox series, also extended an invitation to Katt to come to his office so that they can discuss his issues.

He also put Katt on notice by letting him know the next time he sees him – he’s going to say everything he said in the video below to his face.

Rel Howery noted that he has no intentions of trying to get physical, but he needs to have a man-to-man convo with Katt.
