Britney Spears is hitting her emotional breaking point and desperately trying to conquer that inner torment with marathon sex sessions.
That's what Isaac Cohen reveals in a new interview, having dated the pop princess for about a month. And apparently doing her quite frequently.
Tthe man who had been sharing her bed since her marriage to Kevin Federline fell apart tells London's News of the World that her life is in shambles.
Isaac Cohen reveals how Britney Spears....
- ... Stripped naked and beckoned him to join her for an al-fresco romp in a moonlit Jacuzzi.
- ... Made him dizzy romping on a revolving bed while watching themselves in the mirrored ceiling.
- ... Loved having all-night sex in her marital bed as her wedding dress hung framed on the wall outside.
- ... Crumbled inside when the sex stopped, as she struggled to cope with a bitter divorce and the fear her children could be taken away.
Their whirlwind romance collapsed just a week ago, and sources say Britney Spears has already found a new admirer.
But Isaac Cohen says it's just a phase. A really hot phase.
"She loves sex and is incredibly adventurous. She was totally happy when we were locked in each other's arms. But once the sex stopped Britney was like a little girl lost, unable to cope," he said.
"She would lie like a limp rag doll in my arms and and say, â€˜Why can't everyone leave me alone?' â€˜What have I done to deserve this?'"
Spears, who was first married to childhood friend Jason Alexander for 55 hours before it was annulled, lasted two years with her next husband.
She and FedEx have sons Sean Preston, 1, and Jayden James, four months.
Things were going well for a time, but Britney reportedly grew tired of hearing rumours about FedEx's womanizing. He may or may not have been banging Kendra Jade - but Cohen says K-Fed was definitely tapping some ass on the side.
In the weeks leading up to her first date with Isaac Cohen last December, Britney was branded a bad mother when she was photographed night after night partying until the early hours with new BFF Paris Hilton.
Her family was horrified when she was photographed three times stepping out of cars with no pants, leading to some nude pictures - specifically, an incredible crotch shot sequence that will forever live in Hollywood Gossip infamy.
"By the time I met Britney, she was burnt out," Cohen said. "She knew she had been drinking and partying as a way to try to banish the bad stuff from her life. Far from the trashy drunk, I saw a very shy, sweet girl who was just desperately sad about what had happened with her marriage."
Cohen then talked at length about Britney Spears' undying thirst for booze and sex... and how weird it was the first time he hit that.
"Yes she enjoyed Jack Daniel's, but she was trying not to get in the state she had been in with Paris. Her boys mean everything to her and she worried she might lose them in a custody battle."
"It was clear she was not over her marriage."
"The first time she invited me to her home I saw her wedding dress hung on the wall in a glass box. As we made love that night it was like Kevin Federline was in bed beside us. She had not even begun to move on with her life."
When Britney decided to clean up her act at an Arizona health spa, Isaac went too.
"She needed me to hold her and tell her what a beautiful girl she is. We would make slow love until the sun came up. She has an amazing body and I loved exploring every inch of it."
In January, Britney surprised him by flying them to Las Vegas to stay at Hugh Hefner's exclusive Sky Villa in the Palms Hotel.
At a whopping $40,000 a night, the two-story suite has a rotating bed, with mirrored ceiling and an infinity Jacuzzi spa bath on the rooftop.
Cohen barely got to appareciate the suite, seeing as he was getting it on the whole time.
"Britney is not shy about her body so she slowly stripped off her clothes and beckoned me to join her under the stars in the pool," he said.
"It was an amazing view over the Las Vegas strip. But we didn't stay long, as we wanted to try out the bed."
"We clambered on and I grabbed the remote and started it turning round and round. All the time as we made love we watched ourselves in the mirrored ceiling. It was amazing, but we did it so many times it made us start to feel sick. We had to turn it off."
Britney Spears was also racked with insecurity about her looks.
"Like any woman who has had two children, she worried about her figure. As far as I was concerned she was gorgeous, but she had such low self esteem, she sometimes would not listen."
"She would say, â€˜Am I fat? Am I fat?' then spend hours dancing around the house trying to burn off calories."
"She was always jumping around. Other times, she got so low she didn't care what she looked like. She could not care less some days if she went out of the house without brushing her hair or checking to see if her outfit matched."
"That's just where she was in her life. She had so much on her plate with the children she had precious little time to worry about how she looked.
Isaac then described the passing of Britney's aunt, and the effect it had on their relationship.
"It was around that time her aunt died and that totally devastated her. It was yet another blow. It was me she turned to for comfort and me who travelled to Louisiana for the funeral."
"I rarely saw Britney with any friends and during our time together I never saw her with Paris, it was like that was a part of her life she wanted to forget."
But it soon became clear that as hard as he tried, Isaac Cohen could not cope with the demands of Britney's troubled and hectic life.
And so last week, in an emotional phone call, the couple put an end to their six-week romance.
"I adore Britney and in a different place at a different time we might have stood a chance," Isaac Cohen laments. "It was far too soon for her to get involved in a relationship with anyone."
"But she has coped with so much in her life I hope she does not give up now. She is too special for that."
