Hollywood hunk GERARD BUTLER credits his mother with keeping him grounded – because she refuses to treat him like a movie star.

The actor makes regular trips to his parents’ home in Glasgow, Scotland, where his mother insists he helps out around the house, and carries out his share of the chores.

Butler reveals, “I go home and they’ll cook Christmas ­dinner, and she’s like, ‘C’mon, give a hand, come on, wash the dishes or put the dishes away.’ “And I’m like, ‘Mum, I am a major Hollywood movie star, I can’t be doing this. It’s embarrassing.'”

But mum always wins: “I end up on my hands and knees, wiping up the floor.”
