The Real Housewives of Atlanta season 5 newcomers Kenya Moore and Porsha Stewart had an ongoing feud on-camera, and now Moore may have taken it to Twitter.

Less than a month after Stewart launched her Go Naked hair weave line, Moore wrote several cryptic messages on Twitter suggesting she may have been throwing digs at Stewart's business venture.

"#teamtwirl I'm excited about my hair care line. I'm not selling fake hair. ...shampoo, conditioner, etc. 2grow #realhairlonger #twirlonthat," Moore wrote on the social media site.

After one follower commented, "porsha shade" and another wrote, "so immature like seriously grow up always throwing shade at Porsha," the former Miss Universe pageant made a dig at a hair line.

"I actually embark on business ventures that make sense... With a business plan that can will grow wealth and an empire #not$10abundle,"Moore tweeted.

Stewart launched a website for her new Go Naked hair line in August. She sold the brand in-person to her fans at the Bronner Brothers beauty convention in Atlanta in August. Stewart posed in the nude in an advertisement that is prominently displayed on her website. In the promotional ad, the reality star is completely in the buff and thanks to strategic styling, she is wearing hair extensions that are long enough to cover up her bare chest.

The text on the ad reads: "Clothing is optional. Hair is not. ...I've found that the most beautiful women in the world are the ones that wear nothing but confidence. Women that go NAKED - Porsha Stewart."

Moore also had a feud with Phaedra Parks during season 5 after they failed to reach an agreement on a joint DVD business idea. They ended their friendship when their competing booty DVDs arrived in stores. Parks and her husband Apollo Nido both star in Donkey Booty DVD. Moore later released Stallion Booty Boot Camp. 

Their feud recently escalated when TMZ reported Nida had a physical altercation with Moore's assistant Brandon DeShazer last week.

TMZ reported on Sept. 6 that Nida, a convicted felon, "violently attacked" Moore's assistant, DeShazer. Sources told the gossip site the fight stemmed from their ongoing feud over Parks and Moore's competing booty DVDs. Parks and Nido both star in Donkey Booty DVD and Moore later released Stallion Booty Boot Camp.

Nida, however, told a different tale. He told TMZ when there was a fight between two other men during filming and when he tried to break it up, he was attacked by DeShazer.
