Jessica Simpson almost broke down in tears during an interview with Oprah Winfrey after the TV titan quizzed her over comments John Mayer made about their sex life.
The rocker came under fire last month (Feb10) over his racy interview with Playboy magazine in which he described the singer as "crazy" in bed and compared their lovemaking to "sexual napalm".
He added, "(Simpson was like) a drug. And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me."
Simpson subsequently refused to comment, and Mayer later apologised to his former lover - branding himself an "a**hole".
But during an interview with Winfrey, the media mogul asked Simpson how she felt about Mayer's remarks - and the singer looked distressed when answering, "I don't want people to know how I am in bed."
Simpson then responded to the talk show queen's questions about media speculation over her fluctuating weight, saying: "It's a really hard thing for me to talk about."
The full interview will be broadcast in the U.S. on Wednesday (03Mar10).
