The Bachelor star Arie Luyendyk Jr. is letting the world know what he thinks about former friend Jef Holm's recent slams.

"[Jef] is throwing a lot of shade, but we haven't talked in four years since [Sean Lowe's] wedding," Arie, 36, told Access Hollywood. "I have so much to concentrate on with this and I'm just trying to stay positive. Negativity is -- I'm just concentrating on me."

Arie and Jef became close friends on The Bachelorette's eighth season when they both competed for Emily Maynard. (Jef won Emily's heart and Arie finished as the runner-up).

Following The Bachelor's Season 22 premiere on January 1, Jef took to Twitter and bashed Arie by writing, "Doesn't matter who gets out of the limo...I'll give 5k to the charity of @chrisbharrison's choice if @ariejr lasts 1 year with anyone."

Jef apparently believes Arie and his The Bachelor winner -- or fiancee -- won't make it much longer than he did with Emily. After Emily's The Bachelorette finale aired in July 2012, she and Jef announced their split less than three months later.

When asked why Jef is so "bitter" towards him, Arie replied, "I have no clue. That kind of a question is for him more than me."

Also in response to Jef's latest tweet, Arie told Entertainment Tonight on Wednesday, "He would have lost his own bet, I guess," before adding, "I'm concentrating on me and this whole experience. I'm not even going to get into that."

Shortly after Arie was named the new The Bachelor star in September 2017, Jef said he stopped being friends with Arie years ago because "he's disgusting."

Jef subsequently tweeted, "Oh the stories I could tell..." and said he'd rather see a "double Bachelor" on the franchise instead of just Arie.

Arie didn't have much to say about his failed friendship with Jef in December, telling reporters, "I think when you're on the show with somebody, you really get to know them in that environment. And so, outside of the show, we just realized we weren't really that great of friends."

According to an Us Weekly source, Arie was very sincere while filming The Bachelor no matter what might have happened in his past.

Arie has "no interest in being famous" at all, the source explained. "He wanted to get in and get out. He would be happy to have done this and not televise it. He's an old school Bachelor. He wanted to get in, find his soul mate and go back to his old life."
