“The Bachelorette” 2015 couple Kaitlyn Bristowe and Shawn Booth are never getting married if the latter’s father is to be believed.

When Shawn Booth's father Steve found out about the engagement, he was reportedly enraged. It was said that he had little faith that a relationship which started on a reality television will work out.

"He has little to no confidence in Shawn's relationship to Kaitlyn Bristowe and he thinks that Kaitlyn is 'too fickle,'" an insider told Celeb Dirty Laundry.

"Steve said, 'What the hell's going on? This is nuts!'"

The publication further reported that Steve has been very vocal of his distaste on his son's fiancé. The father reportedly believed that Bristowe could never make his son happy.

"Steve is worried about this, because he's in deep," the insider added.

"He wants Shawn to be happy, but he's worried Kaitlyn is too fickle and flighty. Shawn said his dad's definitely a bit of a skeptic, but he values his advice more than anyone's in the entire world."

Meanwhile, Kaitlyn Bristowe and Shawn Booth have reportedly landed several endorsements after winning "The Bachelorette" 2015. The happy couple is reportedly earning a lot more money than ever before.

Because of their huge following, multiple brands have reportedly tapped the couple into being their ambassadors.

"These Bachelors and Bachelorettes; they have these insanely dedicated followings that pretty much have invested months of time into their personal well-being," an insider told Radar Online.

"They're constantly interested in what they're up to," the source says.

"Now that people see that her and Shawn are this made couple that actually work and are quirky and cool, it's still very marketable."

Kaitlyn Bristowe may have not always been a fan favorite but sources claimed that this trait actually worked to her advantage.

"It leaves her in a place where she is separated and it makes her original, rather than just another blonde girl that walks through 'The Bachelor/Bachelorette.'"
