Manigault-Stallworth, who competed on the reality series "The Apprentice," appeared on Williams' new Fox morning talk show Monday to promote her latest book, "The Bitch Switch."

But media reports said the interview quickly went off-track and developed into a squabble between the two women.

Williams told "Inside Edition," "I'm sad for Omarosa."

Asked if she would ever have Manigault-Stallworth on her show as a guest again, Williams said: "For what? For what? What do I need to have her back on here for?"

Manigault-Stallworth also spoke to "Inside Edition," insisting: "I'm real. Unfortunately, Wendy is a phony. ... You know it was time for someone to go toe to toe with Wendy. She's been doing this for a long time, trying to destroy people and this time she met her match."
