'Apprentice' Hope: 'NeNe Leakes is unstable'

Celebrity Apprentice star Hope Dworaczyk has spoken out about fellow contestant NeNe Leakes, describing the Real Housewives of Atlanta star as "unstable".

The 2010 Playmate of the Year insisted that she originally got on well with Leakes until she saw a whole new side to the reality star.

"I liked NeNe a lot until I had to be her boss," Dworaczyk told E! Online. "I had to tell her what to do and I don't think anybody wants to take direction from someone who is a lot younger than them."

Dworaczyk said that she never expected Leakes to react in the way that she did, and said that her behaviour was "unpredictable".

"One minute she was crying and opening up about herself and sharing something about the past that's very very personal, and the next minute, she's yelling," Dworaczyk explained. "I think you can call it unstable."

Leakes and fellow contestant Star Jones have been at the centre of a very public feud since filming for the series began.

While Jones herself has refused to comment further on the pair's disagreements, Leakes has slated the former The View panellist on a number of shows and described her as a "backstabber".

The Celebrity Apprentice continues tonight on NBC.
