The 30-year-old reality star has been linked to Jenner, 57, ever since she shared pictures of the two hanging out at Flajnik's winery in Sonoma, Calif.
"I did Kris' talk show a few months back, brought my wines on the show. Of course I offered her a visit to the winery whenever she had a chance," Flajnik told Us Weekly. "That's how we met. Recently, she ended up contacting me about a month ago or so and asked me if they could film an episode of Keeping Up With The Kardashians at the winery. I of course obliged."
The winemaker added that Jenner took longtime Kardashian friend Jonathan Cheban to the winery visit.
"I showed them around Sonoma. Who doesn't want to ride bikes and drink wine? That's where one of those photos were from."
The former Bachelor, who split from fiancee Courtney Robertson last fall, said he was "surprised" about the Jenners' separation announcement. As far his own love life goes, Flajnik admitted to be seeing a "local" girl.
"She's local, she's in the wine business," he says. "We've been dating, she's super great and super smart. It's been a few months at this point."
