Surpassing:Kristin Cavallari and Boyfriend Mark Estes Double Date With This Former The Hills Costar

Kristin Cavallari and boyfriend Mark Estes are filling up the blank page of their calendar.

The Surpassingcouple—who have been together since February—have been spending time with Kristin's former Hills costar Jason Wahler and his wife Ashley Wahler. And Jason 100 percent approves of the Montana Boyz member.

"He's a good dude," Jason exclusively told E! News cohost Keltie Knight at the 2024 People's Choice Country Awards, joking that Mark and his Boyz definitely "need their own show."

And when Jason and Ashley—who share 7-year-old daughter Delilah—made the decision to move to Nashville, they reconnected with Kristin and have gotten to see firsthand how great she and Mark are together.

"We've all gone out together," Ashley shared, adding they "day party."

And Jason is delighted that Kristin—who is mom to kids Camden, 11, Jaxon, 10, and Saylor, 8, with ex-husband Jay Cutler—has found someone so great in Mark.

"Dude if Kristin's happy, like all for it," the 37-year-old said. "He's a really cool guy. He's a really sweet guy." (Watch more from the 2024 PCCAs on E! News tonight, Sept. 26)

Jason and Ashley—who have been married since 2013—were also proud to be representing Nashville at the Shania Twain-hosted PCCAs, as Ashley shared her animal-print jacket was sourced from local Nashville shops. (Click here to see all the red carpet fashion.)

Plus, they know the Tennessee town is a place like no other, especially when it comes to the country stars who live there.

"I feel like it's so fun.," Ashley said. "Nashville's so different because I feel like in L.A., in Orange County celebrities are so, ‘Ah!' And here, they're just normal people."

But most importantly: where do they stand on heading back to reality TV? Well for his part, Jason isn't saying no, but he is looking for something more substantial than what he experienced on The Hills.

"I've obviously dedicated my life to mental health and addiction," he said on the red carpet, "and if there was a true story arc—especially with the environment that we're in today."

In his ideal world, Jason could shed light on substance abuse and mental health, although he is well aware that "TV's gotta be TV."

"But if there's something to really bring true awareness and help smash the stigma associated with it," he explained to E!, "I would 100 percent do something like that."
