Fans of Maksim Chmerkovskiy from "Dancing With the Stars" were shocked when they learned he wasn't dancing in the ballroom during the Oct. 2 episode. Now, a new report claims that the reason he didn't dance had to do with issues he's been facing as he works with his celebrity partner, Vanessa Lachey.

According to People Magazine, the "personal issue" that was mentioned at the beginning of the episode and used to explain Maks' absence—which fans later learned had been throughout the week, as rehearsal packages showed Vanessa dancing with Alan Bersten—was a fabrication, and in fact, had to do with some alleged constant fighting that has gone on behind the scenes between the two teammates.

"There's a big chemistry issue," a source told the publication. "They both have big personalities and that's not always the best recipe for a good partnership."

"They've been fighting a lot," the source added.

Neither Chmerkovskiy nor Lachey have responded to the report, though Lachey did take to Instagram after the show to thank Bersten for stepping in and working with her on her "guilty pleasure" routine, which earned a total score of 23/30 from the judges. In the caption, she also indicated that Maks would be working with her again for next week's show.

This isn't the first time a report has circulated however which claimed that there were problems amongst the cast with Vanessa being on the show.

Gossip Cop previously shut down a false report from Star Magazine that claimed that host Erin Andrews had issues with Vanessa because she feared she was gunning for her job. Andrews, who danced with Maks in Season 10 of the show, has been hosting since Season 18, after replacing former champion Brooke Burke-Charvet, who hosted Seasons 10-17.

The false report indicated that "Erin wants Vanessa out of there as quickly as possible. She's worried that the longer Vanessa's around, the more time she has to network and work her magic." It was deemed to be untrue, with Gossip Cop saying that not only was Andrews' job secure, but Vanessa had no interest in taking over as a potential co-host.

Maks has previously admitted to issues with some of his celebrity partners in the past, most notably, soccer star Hope Solo, whom he danced with in the show's 13th season. In an appearance on "The Real" back in 2015, he admitted she was the only person that he could "dislike from my past, present or future."

His absence during this week was also notable because he was taken out by an injury early on in Season 24. After injuring his calf, he was forced to take a break from the competition for several weeks, with Bersten filling in as a pro with Maks' partner, Heather Morris. He returned in Week 6 of the competition and the reunion earned the duo their first perfect score of the season. However, they were shockingly eliminated at the end of the night. Fans who missed his presence in Season 24 won't want to see him missing again for Season 25.

"Dancing With the Stars" airs Mondays at 8 p.m. EDT on ABC.
