"The Bachelorette" star Kaitlyn Bristowe fiancé Shawn Booth has been accused of harbouring feelings for his ex girlfriend, and a new report claims that he tried to contact her shortly after he got engaged.

Two weeks before the finale episode of "The Bachelorette" was aired, Booth tried to reach out to his ex girlfriend, but she did not encourage him, claims an OK!Magazine report, adding that he texted her to say he was "technically" engaged.

The media outlet also claimed that Booth still had feelings for his ex.

Reportedly, the former couple, who first met in college, dated on and off for six years before finally calling it quits in 2012. Although Booth wanted to get her back, he had no such luck, a source revealed, adding that their final break up came after Booth moved for his job.

"She couldn't stand being away from home," the insider said. "Their plan was to get married, but they couldn't agree on a permanent living situation and were forced to break up."

Booth's jealousy was also a contributing factor, the source noted.

Fans of "The Bachelorette" are already aware of Booth's issues with jealousy, as the previous season of the dating reality show saw Booth butting heads with Nick Viall after Bristowe admitted to sleeping with him.

The couple has no immediate plans to walk down the aisle, but they expressed a desire to start a large family. In a chat with People, Bristowe said she wanted four children.

"I have such baby fever," Bristowe said. "I want four [kids]. Shawn wants five. And I hope to God I have all boys." Booth added, "One girl that looks like her mom!"

Regarding their wedding plans, Booth said:"We just want to enjoy the moment right now. It's been so crazy. We just want to hang out as a normal couple, do a little traveling and then sit down and start making some plans."
