During the Real Housewives of Beverly Hills reunion on March 25, the reality stars never held back and constantly called each other out.

Lisa Vanderpump, a contestant on Dancing With the Stars, heated up the conversation hosted by Bravo's Andy Cohen when she started discussing Kyle Richards' friendship with Adrienne Maloof.

Vanderpump claimed it was a "business transaction," according to Radar Online, because Maloof's husband was selling her and Maloof's mansion after the divorce.

On a clip in The Huffington Post, Vanderpump claimed Richards was friends with Maloof only because she wanted the listing on Maloof's house.

"I knew a lot of it was based around this whole business decision because they wanted the listing on Adrienne's house," Lisa explained. "It was a business relationship that needed to be nurtured."

Richards wasn't having it. "That is attacking my character," Richards said. She said of the mansion, "I don't give a s*** about that, OK?"

Maloof left the show at the end of the most recent season. Vanderpump claimed that she felt like Richards dropped her as a friend after Richards sold Vanderpump's house, while Richards said she felt replaced by Brandi Glanville.
