'The gloves are off': Brandi Glanville and Vivica Fox engaging in 'epic screaming matches amid cheating allegations' on Celebrity Apprentice



They've been filming for less than one month, but already there are rumours of rivalry and jealousy on the set of Celebrity Apprentice 7.



RadarOnline reports that outspoken Real Housewives Of Beverly Hills star Brandi Glanville is furiously butting heads with actress Vivica Fox, with the two women apparently 'at war' as they compete in the contest that raises money for charity.



Despite the fact that the pair were acquaintances on friendly terms prior to filming, with their paths having crossed on the LA social circuit on a number of occasions over the years, the show has reportedly brought out the worst in them both.

'Brandi and Vivica have known each other socially in Los Angeles for years, and always got along. They certainly weren't best friends, but had mutual respect for each other,' a source exclusively

tells Radar.



'Fast forward to both ladies filming for Celebrity Apprentice, and the gloves are off. There have been allegations of cheating and lying between the two, and they have had epic screaming matches.'



Seemingly feeling that she has a lot to prove, 41-year-old Brandi has reportedly been struggling during the taping of the NBC series.

Radar previously broke the story that the mom-of-two was 'reprimanded for her behaviour' after allegedly turning to 'booze and Xanax to handle the stress'.



'Brandi is really going to surprise people': A source tells RadarOnline that the feisty blonde has impressed boss Donald Trump, with the business magnate having 'a lot of admiration for her grit and street smarts'

Earlier this month, the website alleged that the feisty blonde 'was sent to [her] hotel to get herself together' after telling boss Donald Trump that she was 'crumbling under the pressure'.



However, it appears that she took their direction and is now a force to be reckoned with, cementing her status as the one to watch this season.



'Brandi is really going to surprise people... anyone that thinks she is a stupid airhead will be shocked when they see her on the show,' the source tells Radar.



A worthy adversary: The actress is also a standout among this season's cast, with the source reporting that both women will likely 'go very far in the show and do very well'

'Donald Trump has a lot of admiration for her grit and street smarts,' they continue, adding that

Kill Bill star Vivica, 49, is a worthy adversary: 'Expect both ladies to go very far in the show and

do very well.'



While it hasn't yet been announced when the show will begin airing, viewers can expect plenty of fireworks from the diverse cast.



Other stars going head-to-head this season include reality star Kate Gosselin, retired Olympic gymnast Shawn Johnson, soap opera star Lorenzo Lamas, Real Housewives Of Atlanta favourite Kenya Moore and former Beverly Hills, 90210 heartthrob Ian Ziering.
