*Chris Rock incurred the wrath of Gabourey Sidibe’s father Thursday when he took liberties with the actress’ backside during the third annual Essence Black Women in Hollywood event.

The “Precious” star, who is nominated for a Best Actress Oscar at Sunday’s Academy Awards, got a shock when Rock gave her the two-handed booty grab as she made her way to the stage.

The actress laughed and brushed it off with a playful slap, but Gabby’s daddy wasn’t so forgiving.

She tells ET Online, “As I go up to get my award in a room where my dad is, because he’s one of my dates, Chris Rock grabbed my butt with both of his hands – and then I slapped him back. I didn’t think too much of it at all, but my dad was super p**sed.”

As for Rock copping a feel at her expense, Sidibe quips, “Some dudes gotta have it – it’s my own fault for being too damn fine.”
