Following recent allegations that Maksim Chmerkovskiy and Vanessa Lachey have been feuding hardcore behind the scenes of Dancing With the Stars, Entertainment Tonight is revealing that they’re staying together — and trying to push through their attitudes!

In fact, yesterday Maks tweeted an apology to Vanessa after he skipped out on Monday’s show due to a “personal issue.” A source later revealed it was actually because he couldn’t stand rehearsing with Vanessa.

“The producers wouldn’t switch partners because two people aren’t getting along, it’s just par for the course,” the source said to ET. “Drama is expected and part of the show. When you train with someone for so many hours so intensely, tensions can run high — for better or worse. In this case, the intensity led to bickering.”

However, the source said “[Maks] realizes that he messed up. Vanessa isn’t afraid to stand up to him. She’s a very strong woman… He’s on thin ice so you can expect that he’ll be on his best behavior from here one out.”

“He’s one of the most popular pros on Dancing with the Stars,” the source notes. “Maks and Vanessa are continuing to dance together and hopefully they’ll make it all the way to the finals. At the end of the day, Maks is always a professional. This is his job. He just needed personal time away not related to Vanessa.”
