Cheryl Cole sang to cope with the pain of having a huge tattoo on her bum.
The 'Fight For This Love' singer belted out her favourite songs to deal with the pain inflicted during the inking sessions, in which she had two large red roses drawn onto her buttocks to merge with the pair of roses already had on her lower back.
A source told Yahoo omg!: ''Cheryl sang at the top of her voice through her tattoo to dull the pain. She had a good nights' sleep before each session and didn't drink to numb the pain - but she did sing, quite loudly, to help her cope. She was singing her heart out - if someone had recorded it they could have made a fortune from the session!''
It's believed the star paid £14,000 for the intricate etching, which took 55 hours to complete after regular trips to the 'Black Anchor Collective' tattoo studio in California, where it is claimed she formed a close relationship with tattoo artist Nikko.
The source continued: ''Nikko is the most discreet man in tattooing and has been offered a fortune to spill the beans on Cheryl, because he knows a lot, but there is not a chance he would. Cheryl spoke about some of the things that trouble her most; she has a total confidant in Nikko.''
Cheryl's tattoo caused a flurry of criticism after she debuted the body art in a picture posted to Instagram last month.
Hitting back at critics, Cheryl tweeted: ''People are entitled to their own opinion. Personally I've never really concerned myself with other people's body parts! (sic)
''I've had it for seven-eight months but only just had it detailed. I can pretty much safely say I'm now done! (sic)''
