Cheryl Cole has a tattoo on her butt.

The former Girls Aloud singer had previously unveiled a rose inking on her back in February, but her tattoo artist posted an photo on his Instagram account showing the body art covers her rear as well.

Although the star's face isn't in the photograph, the distinctive tattoo makes her recognisable.

Without naming the 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.''

In the past, Cheryl has said the ''painful'' artwork was chosen on a whim rather than a deep meaning, and she had claimed she was ''done with tattoos''.

She previously said: ''It was really painful but I think I'm done with tattoos now. It wasn't for any particular reason, I just liked the design. It took 15 hours in total.''

Fans had seen the ink on her back, but until now had no idea of how far down the piece went.
