“Selling Sunset” star Christine Quinn left Season 2 on good terms with Davina Potratz and Heather Rae Young, but the reality star exclusively revealed to Page Six she has a rift with her pals in Season 3.

“Heather and I get into a fight, and Davina and I get into a fight, so it’s really interesting. The dynamic has changed,” she told us. “Season 3 has quite a cliffhanger in regards to me … something in my personal life.”

Quinn, 31, said that her spat with Potratz, 30, was over a real estate deal that was the “the biggest listing that any woman at the agency has ever had.”

“She brings me on to help her find a client and obviously we have different ways of working, so you know we get into a little tiff about that,” the Netflix star shared.

However, her feud with Young, 32, was not about business, but personal.

Quinn said she would tease her co-star about her relationship with Tarek El Moussa, jokingly calling the couple “Speidi” after Spencer Pratt and Heidi Montag.

“It’s really funny to see Heather’s relationship play out because her and her boyfriend have such an interesting dynamic,” she said. “I call them ‘Speidi’ all the time because it’s like articles all the time about baking cookies, you know, watching movies. It’s ridiculous, so you know, you’re going to see the girls and I just get so tired of it.”

Young and El Moussa, 38, announced their engagement this week.

Quinn isn’t the only one fighting with her castmates on Season 3, though.

The reality star shared that Mary Fitzgerald and Young also have a falling out after Young discusses Chrishell Stause’s divorce to Justin Hartley in the press.

“Mary gets really irritated with her because she does an interview talking about Chrishell and her divorce, basically saying that everything is fine, but she did speak on Heather’s behalf,” Quinn said. “A lot of relationships are really changing.”

Quinn got into hot water recently with Stause, 39, herself for comments she made to Page Six about her split to Hartley, 43.

“We heard that they were in therapy, so obviously there were some issues going on with them,” Quinn previously told us.

Stause said in response on her Instagram, “Let me be VERY clear. She knows absolutely nothing about the situation and is obviously desperate to gain attention by doing so. Anything from her is either a complete lie or total conjecture on her part.”

“I just find it silly. The way that these people hold on to things is just ridiculous,” Quinn told us about cast members holding grudges, adding she and Season 2 newbie Amanza Smith Brown able to put their differences aside more easily than others.

“We may get into little arguments, but at the end of the day we’re still always friends,” she said. “Her and I both learn and live and forgive, so it’s great.”
