MAKSIM CHMERKOVSKIY & VANESSA LACHEY
Lachey and Chmerkovskiy's partnership was one of the most anticipated of the show's 25th season, as her husband, Nick Lachey, is also competing and dancing with Chmerkovskiy's wife, Peta Murgatroyd. But all that love wasn't enough to stop drama from brewing between the two. In an unprecedented move, Chmerkovskiy didn't dance the night of the Oct. 2 show, citing a "personal issue." The explanation raised questions, as both Murgatroyd and Chmerkovskiy's brother Val were still dancing that evening. But a source told PEOPLE that the issue was actually between Chmerkovskiy and Lachey themselves, and that the pair have been "fighting a lot." "There’s a big chemistry issue,” the source told PEOPLE. “They both have big personalities and that’s not always the best recipe for a good partnership.” Professional Alan Bersten stepped in for Chmerkovskiy on Oct. 2, but he'll back next week. A DWTS spokesperson told PEOPLE: "Maks and Vanessa are returning to rehearsals and will be dancing together on next week's show."

AMBER ROSE AND JULIANNE HOUGH
The most recent additions to the DWTS feud club are Rose and Hough; the former accused the latter of "body shaming" her during her salsa to "Booty" with partner Maksim Chmerkovskiy. "Last night was like, they did the commentary, and I, it was a point in the dance where I had to lift my leg up and Maks dipped me and [Julianne] said, 'Oh, I'm uncomfortable,' and instantly I felt, I did feel body shamed," Rose said on her Loveline with Amber Rose radio show. Rose went on to say that she felt Hough had a different reaction to her body than those of other dancers on the show because of "my hips, my ass, my breasts." However, the two cleared things up the next week, when Rose apologized to Hough for leaping to conclusions: “Like I said in the package, when you said that I felt very embarrassed and I felt like you weren’t talking about the dance," said Rose. "But if I misunderstood, then I apologize. I’m a very positive person, I don’t like to argue or bicker or make things weird.” Hough accepted the apology, and told Rose she's solely here to judge her dancing — that's it.

MAKS & HOPE SOLO
They did fairly well in the competition, and sparks flew for Chmerkovskiy and Solo off-stage — but not in a good way. Solo accused her pro partner of being "nasty" and "harshly critical," saying he manhandled her at rehearsals and at one point, slapped her across the face. He denied these allegations. The status of this feud? Over. "I don't like her, and that's the end of it," Chmerkovskiy said of his former partner.

MAKS & THE JUDGES PANEL
Chmerkovskiy always stirs the pot on DWTS, but one of his most memorable moments came back in 2011, when he and Solo received a lower than usual score for their rumba. He then suggested that it might be time for judge Len Goodman to retire, a comment that led Carrie Ann Inaba to call him disrespectful. He went on to tell host Brooke Charvet that "with all due respect, this is my show." Not to worry, however: This tension with the judges is long over, and Chmerkovskiy is back in the ballroom.

MAKS & KIRSTIE ALLEY
These two were tight while they were partners on the show, dancing together for two different seasons — Alley's first season and All-Stars. But things imploded shortly thereafter. "We had a great relationship," Chmerkovskiy said of his former partner. "I thought we had a great relationship. If it was something else, or not, I don't know, but I got a message that now I'm associating with other people that she can't be associated with. I am no longer to be spoken with." Alley responded with a tweet, saying, "Dear Sir..after you have ass raped me there is really no reason to include "I wish you the best".. It's rhetorical." Their relationship hasn't recovered.

CHERYL BURKE & IAN ZIERING
Nearly 10 years after they partnered on season 4, Burke spoke out about their partnership on the podcast Allegedly with Theo Von and Matthew Cole Weiss, saying that Ziering was her least-favorite partner of her then-18 seasons of DWTS and that working with him "made me want to slit my wrists." She later apologized for making a remark that "made light of suicide."

MICHAEL BOLTON & BRUNO TONIOLI
Harsh criticism happens a lot on DWTS, but rarely did someone get it as bad as Bolton did. Tonioli called one of his dances "the worst jive of all 11 seasons," and repeatedly said he "hated it." He then proceeded to give Bolton's dance a 3, a score so low it's hardly ever seen. After he was eliminated, Bolton said he wanted an apology from Tonioli. Spoiler: He's still waiting.

KATE GOSSELIN & TONY DOVOLANI
Gosselin struggled with dance, and Dovolani struggled with teaching the reality mom how to dance. Then Gosselin started to criticize Dovolani's teaching methods, and things really started to hit the fan, with a rehearsal session ending with Dovolani storming out of the room, telling Gosselin that he quit. Though he came back after taking a moment to cool down, it's safe to say the pair didn't end up as BFFs.
