While Ashton Kutcher has come under fire due to allegations of infidelity, new reports suggest Demi Moore might be in the same boat.

According to In Touch, Moore got more than a little friendly with a young pal of Kutcher’s, actor Ben Hollingsworth, one night after picking him up from a party.

“They wound up having sex in the back of the car,” a source claims. “It just kept going from there.”

But not too far, as Hollingsworth reportedly called off the affair soon after. “He was getting to be better friends with Ashton and he felt bad about it,” the source explains.

Sex in a car? Why do we need to know these graphic details, In Touch?

Between knowing Kutcher had sex in a hot tub and Moore in the back seat of a car, it’s as though the two have something against a nice, ol’ bed.
