Kate Gosselin's Ex Slams Her Claims They Never Dated: 'We Were Talking About Our Future!'

Before the premiere of new reality show, Kate Plus Date, Kate Gosselin slammed claims she's dated anyone since her bitter 2009 divorce from ex-husband Jon — and specifically shut down stories she once romanced handsome millionaire Jeff Prescott.

"I didn't date him," she said on Instagram earlier this month, adding not to believe "people who sell stories" because "they are looking for publicity to benefit themselves/their business."

But in an exclusive interview with RadarOnline.com, Dreamstime co-founder and philanthropist Prescott insisted he did indeed date the reality mom of eight for nearly two years — and was once so serious about her, he was looking at homes near the Gosselin abode in Pennsylvania.

"We were talking about our future together," Franklin, Tennessee resident Prescott told RadarOnline.com.

He also said they were ready to go public — very public.

In 2015, he claimed he signed on to film her family's TLC reality show, Kate Plus 8, as the busy mom's boyfriend.

RadarOnline.com has obtained emails from Gosselin to Prescott about filming, and a production contract she asked him to sign.

"She can say she didn't date me, but how do you qualify that if I was supposed to be on her show as her boyfriend?" a fed-up Prescott asked.

Just days before they were scheduled to film a date in New York City in August 2018, the businessman said he got cold feet and promptly ended the relationship.

"I texted her and said, 'I can't do this,'" he recalled, explaining that the rumors surrounding their relationship had already become too overwhelming.

"My family was exposed to it, people were flooding my LinkedIn," the dad of grown children told RadarOnline.com. "It was too much for me."

Prescott is now happily married to fitness model and L.A. Nutrition vice president Jenna Sabacheuskaya.

After years of living a quiet life, Prescott wanted to come forward to shut down Gosselin's claims, especially her insinuation he may have sold stories about her.

"For her to imply I was selling stories - If I was about that, I would have signed up for the show!" he said.

RadarOnline.com first reported the couple's relationship in January 2015.

In May of that year, RadarOnline.com exclusively spotted the pair on a "touchy-feely" date in Philadelphia.

But by three months later, the relationship had ended.

Unfortunately, Gosselin is still single. A source told RadarOnline.com the famous mom did NOT find love on her already-wrapped reality show, which currently airs Mondays on TLC.
