'Real Housewives of Atlanta' star Marlo Hampton says 'the devil' keeps coming in between her and Kenya Moore

• Marlo Hampton's feud with Kenya Moore is reignited on "Real Housewives of Atlanta" season 14.
• Hampton told Insider it is "sad" that the two can't form a lasting friendship.

Ahead of season 14's premiere, "The Real Housewives of Atlanta" star Marlo Hampton told Insider she's "crushed" by her inability to maintain a friendship with her castmate Kenya Moore.

During a trip to South Carolina in season 13, the two reconciled with the help of former housewife Cynthia Bailey. They apologized to one another for previous insults and ambushes and agreed to set their differences aside. The moment appeared to be a turning point for the duo, but the season 14 trailer featured several scenes of them screeching at each other once again.

"It's sad because both of us are strong, Black, Aquarius women, same upbringing. And it's so sad that we can't just really get it together and let it last," said Hampton. "At least two years would've been nice to be friends and be happy, but some kind of way, the devil just keeps coming right in between us."

Hampton becomes a full-time cast member on season 14, after appearing as a friend of the show for several seasons.

The two have had multiple battles on the show. They have sabotaged one another's events, called each other vicious names, and traded jabs on social media. Moore crashed Hampton's wig launch with a marching band chanting the name of her own hair-care line. Hampton attacked Moore's turbulent relationship with her birth mother.

Hampton told Insider she tried her best to be a good friend to Moore. "I tell you no lie. I came in 10 toes down, been an amazing friend to Kenya this season. You're going to see," she said. "I was supportive like no other, loyal like no other. And it just was not reciprocated. It was not given back.

Hampton continued: "I just, I'm like, 'What do I do? I keep trying to be so nice. So sweet. I just keep getting crushed.' So I'm just, I'm over it."

Hampton said while the two castmates are not particularly close today they are "in a good place" and she can "love" Moore "from a distance."

"The Real Housewives of Atlanta" premieres Sunday, May 1 at 8 p.m. ET on Bravo.
