"It's my dream to have vodka with Karan," Varma wrote on the mircoblogging site Twitter.
Johar, who is hosting third season of his chat show "Koffee With Karan" on STAR World, wants to have Varma on his show.
"I will surely call Ram Gopal Varma. I don't know what would be the rating of that show but I just want to clear the air. We are fun loving people. It's fun to be sarcastic through media," Karan had earlier said.
