First Joan Rivers spilled the beans about competing on The Celebrity Apprentice's upcoming second season, and now she's disclosed that her daughter Melissa Rivers makes it to one of the competition's final boardroom sessions.

Joan revealed that Melissa -- a former I'm a Celebrity - Get Me Out of Here! contestant -- makes it "right to the end" of The Celebrity Apprentice's second season during a November 4 appearance on Howard Stern's Sirius radio show, the New York Post reported Sunday.

"Ugh! I'm not supposed to say that," Joan reportedly said before declining to reveal any more details about the competition, which was filmed in New York City earlier this fall.

The 75-year-old comedian had previously disclosed her own participation of The Celebrity Apprentice's second season during an August interview with The Canadian Jewish News.

NBC has yet to formally announce the show's cast, however revealed the alleged identities of the entire 16-celebrity cast in early October.

Prior to her flub, Joan had reportedly declined to answer Stern's questions about the identities of the competition's other cast members.

"NBC made us all sign [a confidentiality agreement]," Rivers told Stern, according to the Post.

The Celebrity Apprentice's second edition is scheduled to premiere on NBC in January.
