Singer responds to John Mayer's remarks

Jessica Simpson has broken her silence following her ex-boyfriend John Mayer‘s comments about their sex life.

The rocker, 32, compared the singer to ‘crack cocaine’ and ‘sexual napalm’ in a recent interview in Playboy magazine.

‘I’m a little bit angry. I don’t want people to know how I am in bed!’ the 29-year-old says on The Oprah Winfrey Show.

John, who split from Jessica in 2007 after a year, has since apologised for being ‘an a***hole’.

In her chat with Oprah, 56, Jessica also admits she has difficulty dealing with criticism over her weight.

‘It’s a really hard thing for me to talk about,’ she says.

Jessica‘s interview on The Oprah Winfrey Show airs in the States on Wednesday.
