JESSICA Simpson is set to appear on Oprah Winfrey‘s US TV chat show!

The singer/actress will sit down with the chat show host to promote her new VH1 show, The Price of Beauty, which premieres on March 15.

And sources say Simpson will likely use Oprah’s show to take revenge on ex-boyfriend John Mayer after he dished the dirt on their failed romance.

“Knowing Oprah, I’m sure she’ll ask Jessica her thoughts about John or her response to him,” dished one insider.

“It’s up to Jessica how she’ll respond. She’s remaining tight-lipped on it at the moment.”

Jessica is set to tape the show this Wednesday, Feb. 24.
