Jessica Simpson blasts John Mayer

Jessica Simpson wants John Mayer to "get his life together".

The singer-and-actress has revealed she hasn't forgiven the 'Gravity' singer - who she dated for nine months until May 2007 - after he described their sex life as "crazy" and hopes he will sort himself out.

Discussing his recent apology over the remarks, she told chat show host Oprah Winfrey: "I haven't written back. I don't accept it... I hope he gets his life together."

Last month, John caused controversy when he gave an interview to Playboy magazine describing Jessica as like "a drug".

He added: "And drugs aren't good for you, if you do lots of them. Yeah, that girl is like crack cocaine to me.

"Sexually it was crazy. That's all I'll say. It was like napalm, sexual napalm."

Although she was "disappointed" by the remarks, the 29-year-old star has admitted it was out of character for John to be like that.

She added: "I was so disappointed in him. That's not the John I knew."

Jessica - who is in between a US dress size four and six - also spoke out about her figure and insists she is happy with her womanly curves and doesn't care what anyone else thinks of her body.

She said on 'The Oprah Winfrey Show': "I love my curves.

"I finally relaxed and I don't care what people have to say about my weight. I think I look great."
