Ashton Kutcher accused ex January Jones of having affair with Bruce Willis

Demi Moore has revealed her ex-husband was so jealous of his former TV star girlfriend’s friendship with Bruce Willis, he accused them of an affair.

Ashton Kutcher was supposedly so jealous of January Jones’ growing friendship with Bruce Willis that he was convinced they were having an affair.

In Demi Moore’s new memoir, Inside Out, the actress recalled Kutcher’s all-consuming jealousy about his then-girlfriend maybe hooking up with Moore’s ex-husband.

“Ashton was convinced they’d had a fling on set,” Moore wrote of Jones, 41, and Willis, 64, who starred together in the 2001 comedy Bandits.

Years later, Moore sat next to Jones at an event and asked her if there was any truth to Kutcher’s paranoia.

“Are you serious?” Moore recalled Jones saying, as she laughed. “I told him a hundred times, I didn’t want to f**k that old man!”

Kutcher dated the former Mad Men actress for three years before breaking up in 2001. Moore and Willis were married from 1987 until 1998, when they separated. They filed for divorce in 2000.

Moore married Kutcher in 2005 but they split six years later amid rumours he had been cheating on her. She claims in her new memoir that Kutcher took advantage of her willingness to participate in threesomes and used that as an excuse to be unfaithful.

“Because we had brought a third party into our relationship, Ashton said, that blurred the lines and, to some extent, justified what he’d done,” she writes, according to Radar, adding it was to “deflect blame.”

Inside Out will be released this week.
