*Popeater.com is reporting that the catfight between “Celebrity Apprentice” rivals Star Jones and NeNe Leakes got so heated that Star had to hire her own security detail to keep the Bravo star at bay.

“NeNe is coming unhinged,” a source close to Star tells the website, adding that during taping the “Real Housewives of Atlanta” star made La Toya Jackson cry and even got in the face of singing legend Dionne Warwick.

But it’s her beef with Star that is particularly nasty. “Clearly, she can’t get along with women, especially other black women. She is losing it,” said the source.

For her part, NeNe isn’t waiting for the show to begin to make known her hatred for Star. As previously reported, she made her feelings known during a visit to “The Wendy Williams Show” this week.

“I’m not feeling Star Jones, I’m sorry. I gave her a chance when I first got there, I did,” she told Wendy, later adding, “I wouldn’t spit on Star if she was on fire.”

A friend of Star’s tells Popeater that Star will rise above the negative. That said, she feels that NeNe could be a physical threat to her, so she has hired her own private security guards.

“Star is a real celebrity, not some cheap reality star who is enjoying 15 minute of fame,” the friend says. “She’s a lawyer and a lady. NeNe can say what she wants about Star, but she doesn’t care now that she knows she’s safe.”

Of course, Donald Trump is loving all of this buzz for the show, which premieres on March 6.

“This is the most dramatic season of ‘The Apprentice’ ever. It might just be the best TV catfight of all time,” a show source tells the website. “Donald Trump loved it. He’s no fool. He knows that this sort of drama is TV gold.”
