Celebrity Big Brother can always be a hotbed of indiscreet bed-hopping, frayed tempers and weird behaviour (see Perez Hilton rubbing his crotch against the garden window last year).
But Megan McKenna may have taken the proverbial biscuit with her latest outburst, and heat has got a crisp tenner on this epic meltdown going down in history as the biggest strop EVER SEEN in the CBB house.

In scenes that should air tonight, we’ll get to see Megan losing her absolute rag at and around some mashed potato, and it’s REALLY funny.
She kicked off during a task that involved eating Smash – the instant mashed potato foodstuff made from ‘potato granules’. Yep, we’re making the same face as you right now – and Spam, which, tbf, does sound grim.
“I’m not joking, I need to eat,” she says, clutching at her hair like a particularly irate dad looking at shelves in B&Q.
“I need to eat FOOD. I. Am. STARVIN’. You think I’m joking? I’m so hungry I want to cry,” she yells while trying to move past Scotty T, who mutters “cool story bro” under his breath as she rushes past.
Megan then tries to get into the Diary Room but her progress is barred by the small matter of someone else already being in there, which does not help her mood one bit.

“Big Bruvver, let me IN! I’m hungry. I’M HUNGRY,” she yells, battering on the button in a brave attempt to gain access.
“ALL I WANNA DO IS HAVE A F**KING PIECE A’TOAST. I’M STARRRRVIN’. YOU FINK I’VE LOST IT NAAH, I’M SICK OV IT, I’VE STAYED UP ALL DAY!”
Stephanie Davis, meanwhile, is on the verge of weeing herself with laughter, and at once point actually falls over in mirth.

We reckon Meg’s meltdown might actually beat Nikki Grahame’s epic ‘Who is she?’ rant of 2006.
Catch it – and loads more mad stuff – tonight at 9pm on Channel 5.

Leo Sayer breaks out of CBB because of dirty pants
Yep, Leo skipped out of the CBB house because of his dirty pants. Erm, every heard of a washing machine L? Sayer popped into the diary room to “humbly request” new underwear as he didn’t want to use the CBB house’s washing facilities. When Big Brother refused, Sayer smashed the fire doors open and proceeded to struggle with two hefty security guards while shouting obscenities. Sounds too good to be true, right? Well, here's some video evidence:

Darryn Lyons weird, lumpy, bumpy "abs"
"WHAT THE HELL IS THAT?" was our general reaction to Darryn Lyon's lumpy, bumpy abs. Unsurprisingly the celebrity photographer admitted on the show that he had undergone a “contouring” procedure to remove fat around his muscles and give impression of abs. WOAH, so they're not natural? Get outta town! No, please, literally get out of town. We're terrified.

Verne Troyer drink driving
Verne Troyer has a head-on collision with the diary room after getting a bit tipsy. Then someone remixed it and set it to dance music. Cheers, internet.

The ultimate nightmare
2015 was the ‘Freak Show’ within a freak show as Katie and Katie buried the hatchet over their shopping task to become a two-headed monster.

Botched boob job agony
Katie needed a little extra support to collect her crown. "They wanted to pull me from the show, I had a really bad medical problem." No kidding.

Perez in panties
Perez Hilton had blazing rows with Calum and Katie. Oh, and danced in his dinosaur pants.

Drawn to each other
Summer 2015 brought us CBB’s best ever bromance. James Hill and Austin Armacost got down and dirty in bed, in play-fights, in a striptease…all over really.

Only this big
Stevi Ritchie revealed nasty secrets about his mini manhood, glow in the dark condoms (they light up your face!) and why sex with fiancé Chloe is like “going through the Dartford Tunnel”.
