It all got a bit heated on This Morning on Monday when Phillip Schofield and Kim Woodburn locked horns over her appearance in Celebrity Big Brother.
Phil and Holly were having a rather stilted conversation with the professional cleaner, probing for info on her time on the reality TV show.
Kim and Phil were getting more and more irate with each other over why Kim was quite so nasty on the show, when Phil referenced a "row she'd had on Celebrity Juice".
So we were all VERY intrigued to know which argument Phillip was talking about.
It was pretty hilarious really - she was trying to say that she was this sweet, calm, kind person that had been totally wronged during her stay in the Celebrity Big Brother house. But she was saying it in this very aggressive, rant-y way.
To be fair, even we could see that Phil was antagonising her a bit. But still. No need for it.
But it has now come to light that the argument in question took place on Celebrity Juice - with Rufus Hound.
And it was this incident that caused him to quit Keith Lemon's popular panel show.
In 2013, Rufus said on a podcast with Richard Herring that they'd had a "personal row that had spiralled out of control" - but that the real reason was the lack of support from the makers of the show.
He said: "She was chatting away to Keith Lemon and he asked her: 'Have you got much coming up?'
"She said: 'I don't think the people who make TV would want me anymore'.
"And I said, genuinely, honestly: 'Don't do yourself down. People will always need a cleaner'.
"She looked at me and said something on the lines of: 'When I want an opinion of a fat man, I'll stand outside Gregg's'.

The comedian from Surrey, who was on the panel show until he quit "mysteriously" in 2012, said: "It was a proper fuck you, an old-fashioned fuck you, and I just sort of laughed to myself that here she was having a dig because I genuinely hadn't meant it as an insult. It really fucking spiralled out of control.
"It ended up really horrible. She was trying to be deliberately personal, and by the point it got to that place, I was like: 'OK, because I'm a stand-up comedian and if you want to start heckling, I'm good at this'. And so I was personal back.
"She basically kept saying I was fat. But I did end up saying: 'That's a bit rich coming from a woman who looks like a face drawn on a deflating party balloon'."
He went on to explain that Kim then "wouldn't leave the building without an apology", and Rufus only did it on the condition that he could have a copy of the tape.
He said: "I know it will never go out. It will never be seen. I will sign whatever it is you need me to sign that says I will never put it on YouTube and I will never show it to people, but I'm sure she started that - by being horrible.
"I want to be able to watch it back, because I want to know for my own peace of mind what happened is how I remember it happened."
But Rufus was never given the tape. Shame - we'd LOVE to see it now!
What do you think Kim is really like? Hard-done-by sweetie pie or foul-mouthed drama queen? Let us know over on Facebook and Twitter.
