Cheryl Cole unveiled a spectacular new tattoo on her back

Cheryl Cole unveiled a spectacular new tattoo on her back as Girls Aloud began their reunion tour in her home town of Newcastle.The 29-year-old joined Kimberley Walsh, Nadine Coyle, Nicola Roberts and Sarah Harding as they arrived on stage on a huge Girls Aloud sign lowered from the roof, showing off their curves in metallic basque-dresses.

In a series of skimpy outfits, including a cropped top and a backless dress, Cheryl revealed a new tattoo of two red roses, across the whole of her lower back.Cheryl, who already has a growing collection of tattoos, including designs on her leg, lower back and the edge of her hand, has previously spoken of her desire to have her entire back inked with body art.She told InStyle magazine: "Tattoos are addictive, they really are. If it was up to me - and I could be brave for one day - I would have my whole back done.

"My friends say 'Cheryl, please, you might regret it' - but to me, it's art."
The girls wore a series of spectacular costumes, including huge angel wings and headdresses, during the show. They wore matching strapless red sequinned gowns, resembling Jessica Rabbit, to perform their final song, I'll Stand By You.The band - who have reunited to celebrate their 10 year anniversary - were emotional as they closed the show.Cheryl later tweeted: "I wish I could find the words to express how I feel right now!! Newcastle was perfect! Thank you #proudgeordie #tentour"
