Kenya Moore may be facing some issues with fellow Bravo TV star Brandi Glanville on the set of their new project, "Celebrity Apprentice."

Moore, the 43-year-old former beauty queen who has shot back into the spotlight on "Real Housewives of Atlanta" may be feuding with "Real Housewives of Beverly Hills" star, 41-year-old Glanville.

"Brandi is obsessed with Kenya, she's been attacking her looks, her attitude and she even said something nasty about Kenya's 'fat butt.' Brandi hates Kenya and every chance she gets she rips into her," a source reportedly told Radar Online. "Everyone thinks Brandi is just starting fights to get better TV time but she's personally attacking Kenya and being really ugly to her. She is out of control with her attitude and is turning her hate on Kenya."

While neither woman has responded to the media reports, Moore did send a cryptic tweet recently.

"If people are trying to pull you down remember they are already beneath you," Moore wrote recently. "Have a blessed day."

Glanville has been the subject of rumors concerning alleged substance abuse to cope with the show, but she recently took to Twitter to deny the claims.

"I'm working on a major network show in NYC I'm working hard," Glanville tweeted. "I am not "drinking &or drugging" the cameras don't lie, so just watch &see :)."

Moore is also the topic of media reports surrounding a physical altercation with her fellow "Real Housewives of Atlanta" cast member Porsha Williams. The former beauty queen was allegedly assaulted by Williams, 32, after the former reportedly continued to mock the latter's public divorce from former NFL player Kordell Stewart.

After sources like Radar Online, Us Weekly and TMZ shared the news complete with accounts of what took place from anonymous witnesses, Moore spoke up about the matter on Twitter.

"#TeamTwirl one thing u will NEVER see me do is fight," Moore tweeted. "Your brain and tongue are your most powerful weapons."
