Selling Sunset fans already knew that Jason Oppenheim has dated Mary Bonnet,

Nicole Young and Chrishell Stause. And during the season 7 reunion,

the Oppenheim Group president revealed they’re not the only agents in his romantic history —

which also includes costar Amanza Smith.

While attached to a lie detector test on the Netflix special, Oppenheim was asked by host Tan France,

“Is there anyone else on this stage that you’ve hooked up with before?”

Oppenheim smiled, and after a long pause, finally said “No.” He then appeared surprised as the test confirmed his statement as true.

Chelsea Lazkani then claimed she’d noticed some “inaccuracies” with the test’s results.

“Is it because I’ve made out with Jason?” Smith asked.

“You’ve made out with Jason?” France replied.

“We’ve been friends for, like, 23 years,” Smith pointed out.

“At some point in that 23 years,” Oppenheim admitted.

“Did you only make out?” France wanted to know. Smith said “No,” and when France asked if they’d “hooked up too,” she responded, “Yes.”

That wasn’t the only personal question Oppenheim faced while in the hot seat.

France also asked whether Oppenheim was still in love with his ex Stause. While Oppenheim denied that he was, the lie detector suggested otherwise, as Stause covered her face with a hand.

Oppenheim and Stause went public with their romance in July 2021, but called it quits in December of that year.

He met his next girlfriend, Marie-Lou Nurk, while vacationing on the Greek island of Mykonos the following summer, and they were together for 10 months before ending their relationship in May 2023, citing the difficulties of being long distance. The German model had been splitting her time between Paris and L.A., where Oppenheim lives.

“I’m just single right now and not wanting to rush into any type of serious relationship honestly,” he told PEOPLE ahead of Selling Sunset’s season 7 premiere earlier this month.

Smith went Instagram official with a new boyfriend in August.

“When I needed you most there you were,” she captioned a Reel in which she and the mystery man kiss. “Love really shows up when you least expect it so grateful for this man! 🙏🏽♥️.”

Smith was married to NFL player Ralph Brown, with whom she shares daughter Noah and son Braker, from 2010 to 2012.

After divorcing, the two shared custody of their children until Brown suddenly went missing in 2019. According to court documents obtained by PEOPLE in October 2021, Smith was officially awarded full custody of Noah and Braker as their father remained missing.

Smith has previously kept her romantic relationships mostly out of the spotlight. In 2022, she opened up to PEOPLE about why she preferred to keep her love life private.

“I want to make sure that when we go public that we’re so 100% sure that nobody can affect the energy of that,” Smith told PEOPLE when speaking about a previous relationship she was in. “We came to the decision together very early on that we didn’t want to be posting about our relationship on social media and being in the public. I don’t know, it’s a slippery slope.”
