Strictly Come Dancing can be full of drama and tension - and it doesn't always stay on the dance-floor.
Behind the glittery performances, the fur often flies with the judges clashing over everything from "fake teeth" to shoulder-pads.
This year's show sees its judging panel made up of Craig Revel Horwood, Shirley Ballas and Motsi Mabuse, and Anton Du Beke, but this has changed a fair bit over the years - with these shakeups often being the cause of alleged fall-outs.

From allegations of age discrimination, to accusations of one judge being axed for being "s**t at her job", the judges don't hold back when it comes to tearing each other apart, MirrorOnline reports.
The disputes we see on-air are nothing compared to the nasty digs they are said to make about their fellow judges backstage.
Let's take a look at some of Strictly Come Dancing judges' fiercest feuds.
Craig Revel Horwood and Anton Du Beke
Anton Du Beke returned to the show this series, stepping in for Bruno Tonioli.
Strictly fans are convinced Anton has struggled to fit in with established judges, namely Craig.
Craig appeared to make several digs at Anton during the series that had viewers wondering if there was tension behind the scenes.
While critiquing Katie McGlynn's performance, Anton told her: "Luckily for you, I didn’t actually notice the mistakes. I might have been jotting something down so you might have got one past me.
"I enjoyed the performance and your acting - you’re a fine actress. You brought that to the performance."
A disgruntled Craig immediately shot back: "Anton, you need to keep a watchful eye, darling."
This wasn't the first time things have been heated between the pair, who also shared an excruciatingly awkward moment in the previous series.
After an Austin Powers-inspired routine, Craig told Anton: "I was slightly distracted with the wig and the fake teeth that you have in."
Mortified, Anton replied: "They’re not fake by the way, they’re my own, darling!"
"They’re not fake?" asked a horrified Craig as the rest of the judges collapsed into giggles. "I’m sorry Anton, I really am sorry."
Anton also gave Craig a telling off when he hit out at host Tess Daly on his book tour.
Craig said: "In those ten or 20 seconds where I have to answer Tess’s quite dull questions actually... I tend to avoid them and not answer if I’m super honest."
Arlene Phillips and Alesha Dixon
Renowned choreographer Arlene was on the Strictly judging panel from its first series in 2004 until 2008.
She was dropped from the show to be replaced by Alesha Dixon, sparking an age row as at 66, she was 35 years older than the Britain's Got Talent judge.
The BBC denied any age discrimination and insisted it was simply trying to refresh the show.
Somewhat tactlessly, Alesha said it was actually younger people - like her - who were subjected to age discrimination.
She told Jonathan Ross: "Personally I don't think it's about ageism, I think that's a load of rubbish.
"I knew nothing, I found out when everyone else did. I was as surprised as everyone else but I took all the flak for it."
Speaking about it in 2021, Arlene admitted she "didn't have the strength" to fight the BBC about the decision, telling the Mail: "'As a woman I should've thought about it, I should've demanded why the woman had gone, and three men remain.
"I should have asked them to analyse it. I should have had the strength to at least ask for reasons and if not getting the reasons, a damn well apology."
She also told the Sod's Law podcast: "Nowadays, they could have given me the chance to resign or build a story around it.
"I didn’t have a contract that automatically rolled on to the next year, but I think it was handled so poorly. You then never forget those moments of turmoil."
Craig Revel Horwood and Arlene Phillips
In her 2016 autobiography, Strictly pro Ola Jordan claimed things were far from friendly between Craig and Arlene.
She even claimed Craig branded Arlene "s**t at her job" during a night out and made a cruel jab regarding her usurping in favour of Alesha, something which would have really stung.
Ola wrote: "'She was s*** at her job and that’s why she went,' Craig said. 'It had nothing to do with ageism.'"
She also claimed Craig called fellow judge Len Goodman a "boring old man".
But Craig denied there was any truth to these claims, telling the Daily Star: "If that’s the only thing they were selling the book on then I’d be scared to read it because it won’t be very interesting.
"The truth is I love Arlene Phillips. Whatever Ola has written about what I said about Arlene is just hearsay and her opinion. I don’t care."
Darcey Bussell and Shirley Ballas
Darcey Bussell, who famously spent her entire dance career with The Royal Ballet, joined the judging panel in 2012.
From the moment head judge Shirley was added to the show in 2017, there were reports of the two women clashing.
The tension was noticeable in week one - when Shirley accidentally called Holby City star Chizzy Akudolu 'Lizzy'.
Darcey burst out laughing and dramatically put her head in her hands, but Shirley got her own back later when she panned Darcey's critique of Joe McFadden's dancing.
"I have to slightly disagree with my learned friend," she said before contradicting Darcey's advice.
The following week, the women were seated at opposite ends of the panel, and viewers claimed to have spotted Darcey once again shaking her head when Shirley was moved to tears by celebrity chef Simon Rimmer's waltz.
Shirley has admitted the two have little in common.
She told Radio Times: "Our backgrounds are worlds apart. I come from a housing estate, the under-privileged if you like, and she comes from privilege."
Show insiders have claimed their personalities clashed from the outset.
One source said, in 2017: "Shirley arrived all guns blazing and that has put Darcey's back up.
"She's theatrical and loud, whereas Darcey is reserved and demure. They are professional and civil towards one another at work but they aren't friends."
However, Darcey shut down the gossip, telling the Telegraph: "Of course I get on with Shirley."
"She's hysterical, she's got a great sense of humour, and I totally respect her amazing amount of knowledge. She's great to be with."
Craig Revel Horwood and Motsi Mabuse
A number of digs launched at Motsi from Craig have left fans wondering if they don't get along.
Sarcastic Craig criticised his fellow judge's outfit several times and shamed her for "screaming in German" throughout the dances.
The first criticism came when he and Motsi were giving their opinion on John Whaite and Johannes Radebe's American Smooth to "I Knew You Were Waiting (For Me)" by George Michael and Aretha Franklin.
As Motsi told Craig she "didn't know what was going on" between the pair of them, as they kept disagreeing with their opinions on the dances, choreographer Craig took aim at her outfit.
"Darling, I know what's going on with you," Craig said as he gestured towards her shoulder pads.
But Motsi quickly fired back: "I'm a queen baby, look at my crown!"
Later on the show, Craig made another dig at his fellow judge, telling her to "be quiet" as they revealed what they thought of Sara Davies and Aljaž Škorjanec's tango - which earned the dancing duo 36 points and a place at the top of the leader-board.
Asked by host Tess Daly what he made of their dance, he fired back: "I'm finding it difficult to talk now because Motsi was screaming in German throughout.
"Can you just be quiet when the dancing is on please, darling?" he added, addressing Motsi directly.
If two digs weren't enough, Craig made one more shady comment about Motsi's bedazzling outfit, after Anton confessed he would love to dance with Motsi backstage.
"I wouldn't do that with Motsi with those shoulder pads," Craig told Anton.
But Motsi shrieked back: "This man is jealous of my shoulder pads!"
