Well, this should make for some awkward television.

season 10 stars Josh Murray and Nick Viall are both joining ABC's new season of Bachelor in Paradise, a source confirms to ET. Murray, 31, and Viall, 35, had some noted bad blood during their season, when Andi Dorfman chose Murray over Viall in the 2014 finale.

Dorfman and Murray, a former professional baseball player, ended up splitting in January 2015. But Murray raised eyebrows when he took a dig at Viall last July, after the software sales executive once again placed runner-up on Bachelorette season 11, when he competed for the heart of Kaitlyn Bristowe.

"Welp, let's see who the next Bachelorette is, 3rd times always a charm, you got this bud," Murray tweeted.

Murray also called Viall "classless and disrespectful" in 2014, after Viall shocked viewers during the controversial After the Final Rose show by revealing he and Dorfman were physically intimate with one another during the season.

"I really don't care for Nick that much," Murray told HuffPost Live. "I think it was a classless move and it was very disrespectful. But I think she handled it with as much class as possible. And that's all we’re doing in this situation, we could really care less about that."

Meanwhile, Viall told ET at the time that he took "full responsibility" for the controversy.

"I was surprised that I said that," Viall told ET in July 2014. "It wasn't just about the sex. It was more -- to me -- about the intimacy ... It wasn't like she owed me anything because that happened."

"What I loved so much about the relationship we had was how much we both talked about our emotional and our mental and physical connection," he added. "I felt good about it."

Still, Murray and Viall appeared to bury the hatchet in September when they posed together at a media event, both smiling widely.

Meanwhile, 29-year-old Dorman seems completely over the experience. Last month, she released a book titled It's Not Okay: Turning Heartbreak into Happily Never After, dishing about her time on reality television. In April, she told Cosmopolitan that the Bachelor was the "stupidest" thing she's been a part of.

"The very first night on The Bachelor, my first season, I remember standing in the rose ceremony room," she recalled. "It's 4:30 in the morning at this point. It's freezing cold, everyone is cold and nervous standing on these risers, and you could hear the teeth chattering and the deep breaths. And I watch Juan Pablo come in with a stack of roses, and I'm thinking, 'This is the stupidest thing I've ever been a part of. I'm standing here cold, my feet hurt, and I'm waiting for a dude I don't know to give me a rose.'"

The attorney from Fulton County, Georgia, also admitted that had she met Murray in an off-camera situation, she probably wouldn't have dated him as long.

"When you go on this show, you put your best foot forward," she explained. "You're introducing yourself to the world, in a way -- why would you want to show your worst qualities? I don't think he hid who he was, but the situations we were in didn't bring out his more negative traits. Like, I didn't know he had a temper because every time he was with me, it was just the two of us in a palace or something. How could you not be happy?"
