Maksim Chmerkovskiy and Dancing with the Stars feuds have gone hand in hand over the years, but in this case, most fans are likely to be on his side.
The combustible pro is none too pleased at Julianne Hough, who guest judged the ABC hit series this week and hinted that he phoned in his performance.
"You can accuse me of a lot of things," said Maksim.
"You can't accuse me of not working hard enough."
Maks' comments came in response to Hough's accusation that he didn't give it all on Monday's "switch up" episode, when he partnered with Danica McKellar.
Suffice it to say, Chmerkovskiy didn't take kindly to that.
Following the blowup, some social media users suggested that Hough may have been taking sides because her brother Derek is still in competition.
"She said it and now she has to own up to it," said Maks.
It was slightly uncomfortable ... not as much so as Erin Andrews grilling Peta and James about whether they're taking and having a baby, but close.
Danica's 68 points out of 80 leaves her exactly in the middle of the pack - solo fifth out of ninth - headed into next week, when she should be safe.
Why? Because she's Danica, and Maks is Maks. Phoning it in? Really? Tell us what you think of Julianne's comment and whether you agree with her or not ...
