*Just nine days into the taping of “Celebrity Apprentice” and there are already reports that cast member NeNe Leakes from “The Real Housewives of Atlanta” is acting like a diva.

TMZ reports…

NeNe has already earned a reputation for being the “difficult one” … after an incident over her makeup this weekend.

We’re told NeNe threw a tantrum because she hated the way her makeup artists dolled her up for the opening interviews — so the “Housewives” star made them start over … but she still wasn’t satisfied.

After two makeovers, NeNe ultimately called the makeup crew off — grabbed some tools and did the whole thing by herself.
