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.
While the brunette beauty - who turned 30 on June 30 - admits her 20s were ''amazing'', she is delighted to see the back of them because it was such a hectic time in her life and she now feels able to spend time chilling out.
Nadine Coyle's Girls Aloud bandmates have congratulated her on her pregnancy.
The 28-year-old star announced she is expecting her first child through social networking site Instagram on Thursday (15.08.13), and her close pals Kimberley Walsh, Nicola Roberts and Sarah Harding have now followed in Cheryl Cole's footsteps by expressing their delight at the news.
Cheryl Cole is reportedly worried her relationship with Tre Holloway is ''fizzling out''.
The 'Fight for This Love' singer is busy recording a new album in the UK while her dancer boyfriend is back in Los Angeles working and the difficulties of being apart for so long is said to be taking its toll on their romance.
