Shia LaBeouf has described his mother as the “sexiest” woman he knows and said if they weren't related he would like to marry her.

The Transformers star is said to have made the series of unusual revelations in an forthcoming interview with Playboy magazine.

Speaking about his mother, Shia said: "Probably the sexiest woman I know is my mother. She's an ethereal angel. Nobody looks like that woman.

“If I could meet my mother and marry her, I would. I would be with my mother now, if she weren't my mother, as sick as that sounds."

Shia also apparently claimed in the June interview that when he was a child his mother and her friends would walk naked around his house.

“That was strange for me, and it was really bizarre when my friends were there," he said.

"You've got your little buds over, and Mom's, like, playing naked connect the dots or whatever.

“She's in the middle of goddess-group time, where it's literally a bunch of naked women tracing auras around one another's bodies with incense and then sitting together and humming for prolonged periods of time."
