It’s one of the great debates of our time - well, since Sunday at least. And since that time we kinda thought Cheryl might have fallen over. Did Cheryl Fernandez-Versini have a nipple slip on The X Factor on Sunday?
A lot of Twitter are pretty sure that they saw Cheryl Fernandez-Versini's nipple while she performed her new single, I Don't Care. SO Let’s examine the evidence.
Here's what Cheryl was wearing on The X Factor last night:
Yeah, it kinda looks like something else might slip there, but it didn't, OK. IT DIDN'T. False alarm.
Now here's Cheryl swooshing around a bit**.
No nipples there, soz internet.
How about this one?
Nope. OK, maybe the illusive nipple wasn't in one of those three Gifs. Maybe it wasn't there at all. Let's throw it open to the floor.
Here are some people from the internet who think they saw a nipple.

Here’s someone that looked really, really, really hard for a nipple. But didn’t see a nipple.

Here’s someone that is kinda glad she didn’t see Cheryl’s nipple.

Nipple slip AND miming? Ooh, double burn.

This girl was actually there and is pretty sure she didn't see Cheryl's nip.

Chezza herself doesn't seem to think her nipple made an appearance. Based on the fact she didn't tweet: "Ooh soz about nipping out me nip and that, pet".

Even Cheryl's Twitter parody (@CherylKerl) didn't reference a slip.

So in conclusion, lots of people think they saw Cheryl's nipple, but most of them probably didn't and if it did make a brief appearance, Cheryl didn't care. And neither should we.
Hang on. Was that it?
If this article hasn't quenched your insatiable thirst for celebrity nipples and lumps, here's 100 of them, in one gallery.
100 celebrity nip slips and bum flashes...
Top 100 boobs, side-boobs, nip-slips and wardrobe malfunctions

Kim Kardashi-boob
To celebrate Kim Kardashian's amazing show of side-boob we thought we'd have a look through some of the (fairly) recent celebrity flashers. Some are accidental, some not so accidental, but all are pretty LOL.BEWARE! The following gallery contains nipples. Famous nipples. You have been warned...

Lindsay Lohan: Actual boobage
Lindsay Lohan has some fairly sizable funbags so it always surprises us when we see the actress sans bra on the red carpet. Here Lohan flashed the wiorld not just a side-boob but she went the whole hog and showed nipple too.Can we just point out how pale Linds' boob is? Missed that bit with the fake tan, did we?

Rihanna: Stealth flasher
Who needs to show off a bit of side-boob when you can show your under-udders, eh?! Rihanna gave fans a treat when she flashed her lower boob at London's Wireless Festival in Hyde Park in 2013

Emma Watson: Naughty witch!
Even the pap who took this pic can't quite believe what they're seeing/snapping. The blurred focus and shaky pic is of Harry Potter star Emma Watson accidentally showing off her nude knicks the London premiere of her film. She must have been chilly-willy!

It's a bit nippy! Elizabeth Hurley
We doubt traditional Indian outfits should have added nipple thrown in but hey, it's Elizabeth Hurley

Overexposed: Lady Gaga
We feel as if we've seen Lady Gaga's naughty nipples more than we've seen our own. FACT

Uh-oh, J-Lo!
Oh dear. You don't expect this sort of malfunction from a swanky Lanvin frock, do you? Unfortunately Jennifer Lopez's nipple saw light and decided to make a run for it

Free publicity: Kelly Brook
When Kelly Brook rocked up at then-boyfriend Jason Statham's film Snatch wearing a barely-there sparkly pink dress, she got the whole world's attention. Side-boob? Tick. Bum? Tick. Crotch covered in matching pink sparkly fabric? TICK

Phil & Grant on tour: Helen Flanagan
Helen Flangan's knickers always look like they're having the best time, don't they?

Oh haiii Nicki's nip!
Why the heck should Nicki MInaj get to sing on stage and get all of the attention! Her little boob decided enough was enough and popped out fo say: "Hey!"

Strapped in: Ellie Goulding
Ellie Goulding strapped those puppies down for the GQ Awards. But we can still see 'em.

Made In Chelsea's Lucy Watson appears to be oblivious to the kicker flashing

Braveheart: Gwyneth Paltrow
Gwyneth Paltrow is actually wearing NO underwear with this dress. NOTHING. She's a braver lady than we are...

Tits up: Rosie Huntington-Whiteley
If we looked like Rosie Huntington-Whiteley, we'd be going about naked everyday

Fla$ha
Why oh why did Ke$ha's mum not tell her to put her pants on before her sausage skin tights?

Sineater
All in all, this is probably one of Sinitta's tamest outfits

Wonky bum: Madonna
We're not quite sure how Madonna's bum has come to be this wonky, but we salute her for being loud and proud

Lana Del Rey-hey!
Racy lady!

Yawn: Katie Price
Katie Price, aka Jordan, could be the subject of her very own top 100 nipple slips and knicer flashes gallery. Watch this space...

One day in Paris
Paris Hilton gives us a glimpse of her next flick

Lady in laceL Jaime Winstone
We know Jaime Winstone's probably trying to make some kind of fashion statement but we don't think it's working out too well. All we can focus on is the black bra and pants

We're gonna lift it, lift it higher: Pixie Geldof
Pixie Geldof's purple lacy maxi is riding up a little too high. She doesn't seem to mind though

Sacked: Lauren Conrad
A shapeless see-through sack. What a great idea for the red carpet, Lauren Conrad

Voila! Courtney Stodden
Courtney stodden's got nothing to hide

Chilly Allen
Lily Allen's see-through panelled gown unfortunately has the panel in precisely the wrong place...

What a load of pleather: Jodie Marsh
Is that a pleather thing we spy under there, Jodie Marsh? That whole outfit (or lack of) looks incredibly sweaty...

Strictly naked: Naomi Campbell
Naomi Campbell's incredible body under this Strictly-esque get-up actually has us a little bit (or a massive bit) jealous

Jessica Rabb-it
Pamela Anderson, surely you might aswell be wearing absolutely nothing?

Oh, pants! Konnie Huq
Black knickers. A mint green see-through dress. Konnie Huq obviously hasn't been reading the red carpet rules of fashion no-no's...

Can you see that thong?
Of course you flippin' well can! Tara Palmer-Tomkinson should have got a tighter maxi skirt

Flashdance
At least Beyonce's realising what's happened and is at least attempting to stop it. Which is more than we can say for the flashing culprit...

Plastic fantastic
Yeah, Tara Reid. Just pretend everything's fine and your boob is not hanging out. If you're gonna fork out for a boob job, you may as well show it off, right?

X-tina
Living up to her namesake, Christina Aguilera works that boot-ay

Ke-knickie
Lil' Kim is only one tug away from displaying Big Kim

On the side
An unfortunate angle doesn't do Tamara Beckwith any favours...

X-rated

Looking back...over her shoulder
Maybe Rachel McAdams should have paid more attention to looking downwards

Courtney Love seems to be wearing one half push-up bra and one half normal

Go to M&S!
Sharon Stone's black tee is emphasising both a camel-toe and no bra. Both of which should not be emphasised

Triple whammy

Feeling nippy
A stray nipple has somehow managed to find its way out of Abbey Clancy's gown

Insecure
How young does Amanda Holden look here? But she should have bought a more secure dress perhaps...

Top class
If we were ever going to show off a boob, it would be in the most classy way possible like Uma Thurman

Whoops-a-booby
Keira Knightley almost (read ALMOST) gets away with it, but we can still see those nips

"See, I am a woman!"
Sharon Osbourne had a really strong point to prove, apparently

Shy and retiring
Boy, Coco Austin, that dress fits really well
