Celebrity Apprentice will live on without Donald Trump if the New York real estate developer and reality TV star decides to run for president.

That's the decision NBC entertainment chairman Rob Greenblatt announced on Sunday.

Trump will have to step away from the show -- which is set to return midseason -- if he seeks office because of FCC equal time requirements.

"It's such a strong franchise," Greenblatt explained. "Not to minimize his [Trump's] presence in it, because we love him.

"But I really do think it's all about the casting of that show and the challenges and if he's not available to us, we're going to have someone really interesting sitting at the head of that boardroom."

It's getting down to the wire on the current season on Celebrity Apprentice. Lil Jon, Marlee Matlin, Meatloaf and John Rich are the contestants still standing, but two of them will be eliminated tonight when the show airs on NBC.

“NeNe is causing trouble on the show,” a source told RadarOnline.com.  “She showed up late to filming and that didn’t win her any friends.”

According to a source, when the cast list was first leaked and NeNe was mentioned, she started making phone calls and telling people that she was one of the celebrities on the show.

And Omarosa – who became the woman America loved-to-hate after appearing on Donald Trump’s Apprentice in 2004 – has been schooling NeNe on how to get ahead on the show.
