Jessica Simpson — AKA “Sexual Napalm” — is headed to The Oprah Winfrey Show next month to promote the series premiere of her eight-part VH1 docuseries The Price of Beauty, and The Gossip Wire is atwitter with whispers that the dimwitted singer/sometime actress will also use the occasion to break her silence on some of John Mayer’s loose-lipped banter about their sex life in his recent interview with Playboy Magazine.

John – who dated Jessica for nine months before splitting in May 2007 – has reportedly attempted to make amends with his ex-girlfriend, but his efforts have so far been unable to win over her manager dad. A furious Joe Simpson reportedly lambasted the “Gravity” singer over his recent comments about the busty blonde in a tense phone call last week.
