Jef Holm, a former close friend of Arie Luyendyk Jr., is not a fan of the new The Bachelor star. In fact, that's a huge understatement.

Jef appeared to first insult Arie after ABC announced September 7 on Good Morning America that the 35-year-old race car driver turned real estate agent from Scottsdale, AZ, will be starring on The Bachelor's 22nd season in 2018.

"Oh the stories I could tell..." Jef tweeted.

And then when The Bachelor creator Mike Fleiss thanked fans on Twitter for having "the most positive reaction" ever to the announcement of Arie's participation, Jef quipped in reply, "I'd rather see a double bachelor."

And that was only the beginning.

Arie and Jef became best friends when they both appeared on Emily Maynard's season of The Bachelorette in 2012. Emily, 31, gave her final rose to Jef, while Arie finished as the runner-up.

The specifics on why Jef and Arie's friendship crashed and burned are unclear, but Jef recently called him "disgusting."

Reality Steve spoiler blogger Steve Carbone posted a screenshot last week of one Twitter user bashing Arie, and he captioned the image with the following sarcastic message: "Most positive reaction the Bachelor has ever had!"

The screenshot featured a follower saying that Arie has a "gnarly reputation" in the Phoenix area and is a "luke-level f-ckboy." The user went on to call Arie's behavior with girls "gross," claiming he used to hook up with "sorority chicks" all the time and "banged a ton of 18-year-olds" while "wing-manning" for his pal Jef.

"Apparently the number of young college girls who have hooked up with [Arie], in one sorority chapter alone, is absolutely obscene. Him and Jef would make regular appearances at their parties," continued the follower.

And that's when Jef decided to put Arie on blast.

"I've actually never even been inside a sorority house," Jef wrote in the comments section of Carbone's post. "As for [Arie]... I stopped being friends with him years ago because he's disgusting."

Jef clearly has a low opinion of Arie, but Emily -- who ended her engagement to Jef in October 2012 -- had nothing but positive things to say when Arie was named the next The Bachelor star.

"I can't think of a better person to be the Bachelor than Arie and I've been hoping this day would come since Season 8 ended!" Emily told Us Weekly last week.

"He's a gentleman through and through and all the girls on his season are lucky to have him. I'll be wishing him nothing but the best because that's absolutely what he deserves!"

Season 17 The Bachelor star, Sean Lowe -- who placed third on Emily's season -- agreed that ABC "couldn't have picked a better guy" than Arie to be the franchise's next leading man.

Jef's current male friends from Bachelor Nation appear to include new roommates Robby Hayes and Chase McNary as well as Luke Pell, Chris Soules, and Josh Murray.
