The only worse people that this could have been taught to are the One D boys, but the fact that Cheryl Cole has learned how to tattoo people and has already started is just not going to end well for anyone. Mostly her own skin.

Cheryl took charge of the needle to ink famed tattoo artist Nikko Hurtado who willingly let her etch a shaky a pair of sunglasses, a heart, two stars and her signature onto his right leg in a bid to help her practice.

In a series of pictures posted to her Instagram account, Cheryl is seen in deep concentration while taking direction from the expert and it seems Cheryl was quite proud of her work and was impressed by her bespoke design as she took to Twitter to share her excitement.

She wrote: 'Today I learned from the best how to tattoo ... You learn something new everyday!!!

'I got to tag the best tattoo artist with my first and last tattoo @nikkohurtado designed bespoke by yours truly. (sic)'

Cheryl shares a close relationship with her tattoo artist Nikko, who famously inked a large vine of roses onto her lower back and bum earlier this year.

The tattoo - which reportedly took a total of 50 hours to complete - received massive attention and was criticised by many commentators and fans on social media. However, the former Girls Aloud star brushed off the backlash, saying: 'People are entitled to their own opinion. I've never really concerned myself with other people's body parts.'

Cheryl also has several other tattoos, including tribal tattoos on her right hand and lower spine, a 'Mrs Cole' marking on the back of her neck, a treble clef and vine leaves wrapped around her right thigh.
