Posted on 2nd March 2010 12:00PMJessica Simpson hates people knowing what she is like in bed.
The singer-and-actress was extremely unhappy with ex-boyfriend John Mayer's recent interview in which he described her as "sexual napalm" because she prefers to keep her private life under wraps.
She said: "I don't want people to know how I am in bed."
The 29-year-old star also spoke about the criticism she has received regarding her fluctuating weight, and almost broke down in tears as she described how much the comments hurt her.
Speaking to US TV talk show host Oprah Winfrey for a programme due to air in the tomorrow (03.03.10), she said: "It's a really hard thing for me to talk about."
Last month, John caused controversy when he gave an interview to Playboy magazine describing Jessica - who he dated for nine months until May 2007 - 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. "
The 32-year-old musician later apologised for the interview, in which he also used the word n****r and admitted to still loving his most recent ex-girlfriend Jennifer Aniston.
