Britney Spears‘ ex-boyfriend Isaac Cohen has described the pop star as “a little girl lost”, unable to cope with the media attention since she announced her split from husband Kevin Federline last November.

Isaac, who reportedly dumped Britney by phone this week, told the News of the World that Britney had already been partying hard for a few weeks by the time he met her in December: “By the time I met Britney she was burnt out. 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.”

“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 was in bed beside us. She had not even begun to move on with her life.”

“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. She would lie like a limp rag doll in my arms and and say, ‘Why can’t everyone leave me alone?’ and, ‘What have I done to deserve this?’”

Isaac added that Britney is still insecure about her post-pregnancy 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, ‘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.”

“Her boys mean everything to her and she worried she might lose them in a custody battle.”

“I adore Britney and in a different place at a different time we might have stood a chance [but] 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.”
