‘Animal House’ star Tim Matheson has revealed he once slept with four women in the same day, including Kirstie Alley.

Matheson made the scorching revelation in his memoir, “Very nice to meet you.” At the time, the actor was dating an Emmy Award-winning actress who remained unnamed in history.

Matheson began the story the day before his 33rd birthday, when he received a visit from a woman he had previously “spent time with.”

“’Hey, hey…’” Matheson recalled in his memoir. “‘So… I know it’s your birthday tomorrow. And… I wanted to give you an early present.’ Opening the door all the way, I decided it would be rude to send her away; we soon became lovers on the downstairs sofa.

Hours later, Matheson received a visit from another woman while his unassuming girlfriend was in New York.

“Now it’s 2:30 p.m., my lover Adam and Eve is long gone, and there is a soft knock at my door again,” he wrote. “This time, at my door, a beautiful waitress I knew who worked a few blocks down the street. ‘I have to work all tomorrow,’ she said, pouting her swollen waitress lips. ‘So I wanted you wish a happy birthday today.’ “How nice,” I said. “What do you have in mind?” She walked in and grabbed my belt.
