We're not quite sure what the eff Cheryl Cole was thinking when she decided to cover her lovely behind in one of the most horrific celebrity tattoos we've ever seen. Not only would it have been a rather embarrassing session in the chair - "could you hold your cheeks apart slightly more please, Ms Cole" - but it must have been pretty damn painful.

Of course, it divided opinion upon its Instagram debut on Sunday, but it was by no means Chez's first time under the artist's needle - the former 'X Factor' judge has quite a history of ill-advised tattoos, as it turns out...

Cheryl Cole

Cheryl was inked even before finding fame on 'Popstars: The Rivals' in 2002, already sporting a butterfly tramp stamp.

She also already had a Tweedy-Pie etched on her bum, as it was her childhood nickname. Nice thong, Chezza!

After finding fame with Girls Aloud, she soon had a barbed wire tat etched around her right thigh, complete with a treble clef, cos she's musical, innit.

Cheryl added to her collection with a (now much-copied) tribal design on the side of her right hand.

She then had 'Mrs C' inked on the back of her neck in honour of her husband Ashley, following their wedding. Bet she regrets that one now.

Cheryl also showed off another design on her bum at the Brits in 2009. Cheeky!

Chez then decided to go large with her tattoos, expanding her back tat with a vine design over her original butterfly, which she revealed at the NTAs 2011.

Then, her 'Call My Name' video released in 2012 seemed to suggest the tattoo continued down her leg. Looks like she's not wiped properly to us.

Then, in 2013, she shocked the world (ok, us) when she revealed her giant rose tattoo while performing with Girls Aloud on their Ten reunion tour, which covered most of her previous tattoos.

But this wasn't the end of it. Oh no. Not by a long shot.

    Anastasia, it's time to book an appointment at the laser removal clinic.

  • Cheryl Cole

    We get it Cheryl - you're an English rose. But do they have to be that <em>big</em>?

  • Chris Brown

    In a move that was ugly on several levels, real-man-impersonator and least-deserving-celebrity-of-all-time Chris Brown got a picture of a woman's battered face tattooed onto his neck months after battering a woman's face with his bare fists.

  • Eminem

    Slim Shady's insistence on putting daughter Hailie Mathers in his songs was bad enough. This tattoo of her is embarrassing parenting taken a step too far.

  • Eva Longoria

    There's nothing wrong with Eva's (now removed) 'Nine' tattoo per say, except that it represents the folly of getting inked in tribute to your partner - in this case basketball player Tony Parker, jersey number 9 - when they end up cheating on you.

  • Harry Styles

    Harry's tatts all look like they've been scribbled on the back of a biology exercise book in Biro by a fidgety teenager. Quite apt, really.

  • Hayden Panettiere

    Like a job application or a witty riposte, the first run of getting words tattooed onto yourself is to make sure it is spelled properly. Heroes star Hayden stumbled at this first hurdle with her Italian phrase which was meant to say 'live without regrets'. She has since admitted regretting the tattoo.

  • Justin Bieber

    Nothing wrong with an owl, we suppose... represents knowledge and wisdom... good at hunting... it's just that this one likes a bit, well, crap.

  • Justin Bieber 2

    ...and while we're at it, Justin, getting the name of your own album tattooed on your arm is a bit naff - not least of all because you're bound to get older and want to move away from your pop origins into making 'proper music'. Just sayin'.

  • Katie Price

    We know Pricey is fond of a wedding, but this is just ridiculous...

  • Liam Payne

    It's one direction alright - down your forearm towards your hand. Why, we have no idea.

  • Louis Tomlinson

    What is it with 1D and their doodles?!

  • Mark Wahlberg

    Irony or no irony, a tattoo of your own name is NEVER cool.

  • Megan Fox

    The problem with getting a line from King Lear tattooed on your back is that everyone, forever, is going to ask about it, and you're going to have to say 'It's a quote from Shakespeare'. Which is a line that's impossible to say without sounding like a pretentious t**t.

  • Mike Tyson

    It's on your face Mike. Enough said.

  • Pamela Anderson

    Would you get a tattoo reminding everyone of your most embarrassing failure? Of course not. So why Pamela Anderson has one that screams: 'I starred Barbed Wire one of the biggest commercially and critical flops of all time', we have no idea.

  • Steve-O

    The Jackass star got his own face tattooed on his back, which is a lot of pain to go through for a joke.

  • Zayn Malik

    "I got a mic on my arm cos, y'know, I'm all about music". O-kay...
