As Celebrity Big Brother gears up to return to our TV screens next week (4 March), we can't help but think of the many iconic moments it's given us over the years.
From Megan McKenna having a meltdown over mashed potato to Gemma Collins telling Gillian McKeith to 'f*** off,' there's been a fair few.
And, who can forget the chaos that ensued Angie Bowie told her fellow housemates that her ex-husband David Bowie had died and Tiffany Pollard thought she meant David Gest, another housemate who'd been resting in bed after feeling unwell?

But, there is one truly unforgettable moment that stands taller than the rest.
Having been part of the Big Brother series from the off, Davina McCall was considered the 'it girl' of presenting, but she took it to a whole new level in Big Brother 6 during Sam Heuston’s exit interview.
Heuston was quite fond of wearing nothing but a bikini while in the house, so McCall hatched a plan to make her exit the funniest and most memorable of the season.

The award-winning TV presenter later went on to explain the situation to BuzzFeed, including her biggest regret during the filming.
She said: "So, Sam who I was interviewing has spent her whole time in the Big Brother house in a bikini and we thought 'what can we do that would be quite funny?'
"Then me and the producer — on our own — said 'let’s not tell anyone'."
They made a plan to keep it hush hush from production until the hilarious reveal.

"Let’s not tell the floor manager, let’s not tell the camera man, let’s not tell the director. No one.
"Let’s go and put a bikini on and then a coat and then, in the ad break, change into the coat and then come back out and go get her from the house."
Davina was very nearly caught out when the floor manager noticed she'd got changed, but they didn't say anything.

She then started the interview and went: "Sam, I’m a bit hot actually," before taking off the coat.
"I stood up and took off my coat and the cameraman who was filming me went like that [looking out at her] from behind his camera in case something was wrong with his camera," she recalled.
But, McCall didn’t think about where the audience would be at the end of her bit.

She joked: "I felt quite confident and I had forgotten that I had to stand up at the end of the interview and everyone was in the circle around me underneath, staring up my arse and at my vagina from the front.
"It was vagina level and I had my cards here over my vajayjay thinking, 'oh this is quite, like brutal' — just trying to do the end piece to the cameras as quickly as possible."
Despite the rather awkward moment, Davina smashed it and the moment went down in reality TV history.
Viewers can catch this year's celebrity housemates entering the Big Brother house on 4 March at 9pm on ITV.
