WHEN Cheryl Cole revealed a hint of a large back tattoo while performing with Girls Aloud earlier this year she shocked her fans.

However, they are likely to be completely stunned after a picture of the whole tattoo has emerged – showing it covers her lower back and her entire backside.

The singer’s tattoo artist posted the eye-popping shot on his Instagram page earlier today.

Without naming his client, Nikko Hurtado wrote: ''Here is a in progress shot of a Tattoo I've been covering up and reworking ... Really exited to show healed shots.

''It was some intense tattooing sessions. She's tough as nails.''

Nikko Hurtado confirmed he is “reworking” the tattoo – although it is not known what exactly Cheryl has in mind.

The former Girls Aloud singer has since taken to her Twitter account to defend her inking decision.
