Jessica Simpson may speak her mind about former boyfriend John Mayer when she makes a guest appearance on Oprah.

The actress, who dated Mayer until 2007, sparked speculation she may settle scores with the singer after he called her “sexual napalm” and likened her to his own personal brand of crack cocaine in a Playboy interview.

According to tvguide.com, the date for the appearance was yet to be set, the New York Post reported.

Representatives for Oprah Winfrey and Simpson refused to confirm if the subject would be touched upon during the upcoming episode.

But sources claimed the chances of Simpson breaking her silence on the topic could not be ruled out.
