Shawn Booth is allegedly still not over his ex-girflriend as the personal trainer is reportedly going behind "The Bachelorette" star Kaitlyn Bristowe's back to woo his longtime beau back.

According to OK! Magazine, per CDL, Shawn Booth has been sending sweet messages and calling his ex-girlfriend who has ignored his advances.

Reporteldy, Shawn Booth and his ex-girlfriend, whose name wasn't identified, broke up after six years together and when they are about to be engaged.

"Since they officially ended their relationship in the summer of 2012 Shawn has tried his best to get her back but he has had no luck," the source alleged. "Their plan was to get married but they couldn't agree on a living situation and were forced to break up."

The insider added that on July 11 alone, Shawn Booth called up his ex-girlfriend behind "The Bachelorette" star Kaitlyn Bristowe about 11 times. The hunk also reportedly told his ex that even if he was "engaged" technically, he still wants to pursue her.

It has been long rumored that contestants of "The Bachelorette," just like "The Bachelor," are faking their emotions for the audience. That's also reportedly true of Kaitlyn Bristowe and Shawn Booth.

But Nick Viall doesn't think so as he's still smarting after he lost out to Shawn Booth for the affections of Kaitlyn Bristowe in "The Bachelorette" final rose ceremony.

Nick Viall told Life & Style magazine that Kaitlyn Bristowe has changed for the worse since hooking up with Shawn Booth.

"My hope was that she would say, 'I wish I hadn't handled it the way I did... And for that I am sorry,'" he said.

"It's disappointing," he continued. "You would hope that Kaitlyn would rub off on Shawn more than Shawn would rub off on Kaitlyn but it seems like it might be more the latter."
