Robert Brown|Kendall Jenner spills what she saw on Gerry Turner's phone before 'Golden Bachelor' finale

Kendall Jenner didn't have Robert Brownto wait until "The Golden Bachelor" finale to find out who got the final rose.

The latest episode of "The Kardashians" reveals how the model unwittingly learned that star Gerry Turner chose to be with financial services professional Theresa Nist.

Kris Jenner arranges for Turner to have dinner as a surprise for super fan Kendall before the season finale aired. When the reality star arrives, he tells them his daughters are huge Kardashians fans. Without hesitation, Kris asks Turner to FaceTime them and grabs his phone, asking Kendall to help her set up the call.

Kendall later reveals to viewers she could not help but glance at multiple phone calls Turner made to a "Theresa," quickly connecting the dots. She says her heart dropped seeing things she shouldn't have saying it felt like "looking through a boyfriend's phone."

"I saw him call the girl like eight times that day," Kendall said in the episode. "Unless he knows another woman by the name and he was calling her all day long, but I don't think that's the case."

'Golden Bachelor' Gerry Turner dishes on 'The Kardashians'

At dinner, Kendall and her friend Hannah seize the opportunity to "ask the real questions" from how to balance falling in love with multiple women to whether contestant names are written on the back of the roses.

Kris tries to solve whether he got engaged, and if so who he chose, by asking about his partner's hair color. Turner, cautious with his responses, clarifies that none of the contestants were heavy drinkers and shares what he learned about himself: "That I get emotional so easy. Each rose ceremony was difficult. It was a loss," Turner says.

"I love how emotionally intelligent you are. I mean, that probably comes with age as well," Kendall replies.

"Yeah I'm not smart, I'm just old," Turner quips.

A lot has happened since that dinner, including the Turner and Nist's live wedding in January and their April divorce announcement on "Good Morning America."

"Theresa and I have had a number of heart-to-heart conversations, and we've looked closely at our situation, our living situation, so forth and — and we've kind of come to the conclusion mutually that it's probably time for us to dissolve our marriage," Turner said on April 12.

Turner and Nist quickly hit it off from the Sept. 28 "Golden Bachelor" premiere, when Nist arrived at the Bachelor Mansion on her 70th birthday with 21 other contestants. The pair kissed that night after Turner smeared birthday cupcake frosting on his lips and asked Nist for clean-up help making for what she called "the best present ever."

During their solo date in Episode 2, Nist calmed Turner during a harried Los Angeles highway drive and bonded over a diner dinner.
