Tiffany Haddish Says Kevin Hart's Cheating Scandal Won't Come Up On Their Movie Set

Tiffany Haddish is all for giving her co-star, Kevin Hart, a pass on his cheating/extortion scandal because that's HIS deal -- while HER deal is ... let's just be funny, bro.

Tiffany, who's currently shooting a new comedy with Kevin called "Night School" ... was at LAX when we asked her about his situation, and whether it's a distraction on set. Based on her quick response ... it's a non-issue when they're working together.

She also says Kevin ain't special -- lots of guys get extorted. Just for, ummm ... different things.
