Ice Cube has entered the Katt Williams chat days after the comedian shook up showbiz with his "Club Shay Shay" interview ... and, he's looking to clarify the allegation he tried to make light of a rape scene.

Katt accused Rickey Smiley of lying about being the OG pick for his "Money Mike" role in "Friday After Next" -- and also claimed he saved the character from a bathroom rape scene involving Terry Crews' ex-con character, "Damon."

Cube agreed that Rickey lost the part after Katt embodied the pimp schtick to make "Money Mike" an unforgettable character, but denies he ever wrote a rape scene for the film -- he says that's just not his style.

Cube says the main goal of the scene was to cancel out Katt and Terry's characters, as the film had 3 main villains, including the "Santa Claus" role Rickey ended up filling.

The hip hop legend also took some time out to address the ingrates who've groused over the years about their salaries in the 'Friday' franchise.

Cube explained actors aren't the only ones who need to get paid for movies -- producers, stagehands, even the coffee runners have to get paid every day, while most of the actors he employed were done with their scenes after a couple of days.

He's still an actor for hire ... Cubevision doesn't have to create every classic.
