Scene of the ‘crime’: Kutcher was said to have cavorted naked with Leal in the hot tub of the Hard Rock Hotel in San Diego before bedding her

Speaking of the fling, she told The Sun: ‘We had sex twice. Everything felt natural. We were having a good time. He was good, but it wasn’t weird or perverted or creepy.

‘He had good endurance. We were up for a while. It was about two hours.’

In the weeks after the story broke, Kutcher and Moore made apparent attempts to heal their relationship with Kabbalah retreats, including a camping trip to Cachuma Lake near Santa Barbara, California, last month.

The couple were accompanied by some close friends along with their Kabbalah instructor Yehuda Berg and photos emerged of the pair sat around an outdoor fire.

It was first time they were pictured together since news of Kutcher’s alleged booze-fuelled one-night stand broke.

In the weeks that followed, Demi appeared to be suffering under the strain of her marriage breakdown, becoming gaunt and scarily skinny - reportedly dropping down to just 7st (98lbs) which given her height of 5ft 5in is considerably underweight.

The Leal affair was not the first time Kutcher has been accused of being unfaithful to Demi.

Kutcher was first accused of infidelity in September last year, when Brittney Jones, 21, said she had sex with the actor at the Beverly Hills home he once shared with his wife while she was away.

She also later claimed that Kutcher told her he had an open relationship with Demi and they would ‘often engage in threesomes’.

Jones told Star: ‘He looked over our texts and said he wanted me to delete all the messages from him. He then told me he wanted me to delete the texts I had sent to him. He said they could hurt him.’

At the time, the couple, who are worth an estimated £95million, brushed off the allegations.

Kutcher, who took over Charlie Sheen’s role in hit U.S. TV series Two And A Half Men earlier this year, wrote on Twitter at the time: ‘I think Star magazine calling me a "cheater" qualifies as defamation of character. I hope my lawyer agrees.’

He added: ‘Star magazine - you don’t get to stand behind "freedom of the press" when you are writing fiction.’

Kutcher’s spokesman also denied the allegation while Miss Moore tweeted ‘Excellent point my love!’

Moore, who was previously married to Bruce Willis, started dating Kutcher in 2003. They married two years later.

In May last year Demi talked about wanting to start a family with Kutcher in an interview with Elle magazine - something that never came to pass.

The actress has three daughter with her ex Willis - Rumer, 23, Scout, 20, and Tallulah 17.
