Former "Dancing with the Stars" contestant Kelly Osbourne stopped by "The Ellen DeGeneres Show" and turned the tables on the show's host.

"I have a question," said Kelly, transforming from interviewee to interviewer. "Is it true that Portia [de Rossi] is going to do ['Dancing with the Stars']?"

"I heard that Portia DeRossi might be doing 'Dancing with the Stars,'" Ellen replied. The comedienne later confessed: "I don't know if she's going to do it or not. She won't tell me."

Kelly's appearance on "The Ellen DeGeneres Show" airs Friday, November 12.
