The drama between former best friends Tanin Nikpey and Sky Askari is still raw — and according to Nikpey, one private phone call sealed the fate of their fractured friendship.

During an exclusive joint interview with Page Six’s “Virtual Reali-Tea,” Nikpey and her co-star Golnesa “GG” Gharachedaghi opened up about the emotional unraveling viewers have seen play out on Bravo’s “The Valley: Persian Style.”

At the center of the fallout is an eyebrow-raising moment involving Nikpey’s skincare brand, skin by TANIN. Tensions first bubbled up when Askari rubbed one of Nikpey’s signature skin oils on Nikpey’s dog — a move Nikpey found deeply disrespectful. While it was initially brushed off as a joke, Nikpey says Askari’s actions cut much deeper.

The situation escalated at a cast dinner when Reza Farahan revealed just how upset Nikpey was over the incident, igniting a contentious back-and-forth that exposed cracks in the once-tight friendship. Since then, what started as hurt feelings has spiraled into what appears to be an irreparable rift.

Nikpey tells us she attempted to address the issue head-on in a private phone call with Askari — but it didn’t go as she’d hoped.

“I did call her the next day and I did bring all this up and she did not [apologize]. It was very much dismissed. I said, ‘Did you use the oil?’ She said, ‘No, it’s probably going to give me a pimple.’”

For Nikpey, the controversy was never simply about a dog or a beauty product.

“This was way deeper than what [it appeared to be]. Listen, I love dogs. I love dogs. I rescue dogs. Like, there is nothing more important to me than dogs,” she explains.

Gharachedaghi — who admits she was never particularly fond of Askari — didn’t hesitate to back her friend up. In fact, she underscored just how central dogs are in Nikpey’s life and marriage to husband Greg Haroutunian.

“Her husband can’t even sleep in bed with her because her dogs love to sleep there,” Gharachedaghi says with a laugh.

Still, Nikpey insists her hurt stemmed less from the act itself and more from what she perceived as a lack of support.

“It was not about the dogs and it’s not about the oil. It was the questioning of the product and all those things. Listen, if I’m asking you to just be a cheerleader, take a victory lap, say, ‘I’m so excited,’ and we move on.”

As for whether reality TV accelerated the demise of their bond, Nikpey believes the issues were already brewing.

“I think that we had a really solid friendship maybe the first two years. But I think things really started to change a while before this happened. And then this happened maybe at the right time for the show but I think it was all authentic. I do think cameras amplify your problems — or maybe, more so, you see it more clearly,” she shares. 

“I feel like things that I would usually look the other way, it’s, like, now I’m watching and am just like, ‘Wow. Why did I ever do that?’”

“The Valley: Persian Style” — which finished airing its first season on Bravo this week — is available to stream on Peacock.
