Girls Aloud have pledged to have a completely dry tour in solidarity of band mate Sarah Harding, who has struggled with alcohol addiction.

The five-piece have decided that since Sarah can no longer drink alcohol to celebrate their shows, they will all abstain for the duration of the tour, which will see them travel the country from Cheryl's hometown in Newcastle through to Nicola's native Liverpool.

Sarah has struggled with her problems since she parted from her fiancé Tom Crane in 2011, and has since received help to tackle her alcohol problems and depression.

A source told the Sun: "The girls have decided to ban alcohol altogether in support of Sarah. She's still dealing with her alcohol problem two years on – and they've decided to ban it out of respect for her. It’s only fair, they don't want her falling off the wagon and going back to how she was after she split from Tom."

The source added that the rule even applied to all staff and the backing dancers on the tour, so if they want to enjoy a few drinks after the show they have to leave the arena first as the area around the dressing rooms will be completely dry.

The girls could also be hoping the ban will help them to be on tip-top form every night, as there have been plenty of rumours about that the shows will mark the end of their time together as a group.

  • Ant and Dec

    They're beloved of British teatime audiences, but Ant and Dec failed to be adored by US viewers and critics alike when they hosted their US game show, Wanna Bet. It ended up as the nation's 89th most-watched programme. "Comedy sensations? We'll take their word for it", scoffed one TV columnist. (Pic: Getty Images)

  • Hannah Spearitt

    S Club 7 star Hannah Spearitt had a couple of pint-sized roles in US movies (Seed of Chucky, Cody Banks 2). However, La Spearmint is now back in the UK and starring in Primeval, which has only enjoyed tiny success across the pond. (Pic: Getty Images)

  • Jeremy Paxman

    If Simon Cowell can be bigger than Jesus in the States, why can't newsgrumbler Jeremy Paxman? Well, that's what BBC America bigwigs hoped when they came up with the wheeze of giving Paxo his own self-titled show. Sadly, the idea was dropped, and even Newsnight has been axed from the channel in favour of Hotel Inspector repeats. (Pic: Getty Images)

  • Katie Price and Peter Andre

    "We've not come to LA to crack America", protested Katie Price, when rumours that she was being snubbed by members of the Hollywood titterati such as Posh Spice and Paris Hilton started doing the rounds. "Peter's just recording an album here." Because they have no studios in London, clearly. (Pic: Getty Images)

  • Lenny Henry

    Not content with trotting out the same old impressions week after week for the BBC, Lenny Henry attempted to make his name Stateside by starring in 93 minutes of arse-quakingly tedious cinema named True Identity. It was a box office bomb, and the ex Mr Dawn French has stayed at home since. (Pic: Getty Images)

  • Lloyd Owen

    Monarch of the Glen favourite Lloyd Owen thought he'd hit the big time when CBS selected him as the star of their high-falutin' 2007 musical drama series, Viva Laughlin. However, it was chopped after just two appalling episodes, leaving Owen's career promptly kicking the bucket in the land of the free. (Pic: Getty Images)

  • Michelle Ryan

    After leaving the role of genetic pot noodle Zoe Slater in EastEnders, Michelle Ryan thought she'd have a crack at being reborn in the USA. She landed the lead role in a high-profile remake of Bionic Woman, but the show was a duffer and axed after just eight episodes - leaving Michelle booking a ticket on the next Heathrow-bound red-eye.

  • Robbie Williams

    Robbie Williams, the Steve McDonald of Pop, tried to make it big in the US for years - even releasing a swing album featuring Nicole Kidman in a bid to tempt suburban housewives to part with their dollars. But after repeated attempts, the fat dancer failed to "Break America" and later recorded a three-minute moan-athon with that same name. (Pic: Getty Images)

  • Russell Brand

    After Ofcom favourite Russell Brand wooed global audiences with his turn in Forgetting Sarah Marshall, American MTV execs selected him to host their 2008 awards show. Sadly, his slurs against their outgoing president and the Jonas Brothers failed to appeal, and the love machine hasn't been invited back. (Pic: Getty Images)

  • Cheryl Cole

    After three years of trotting out "you were amazing babe" on The X Factor, Simon Cowell decided to take her to LaLa land for the American version of the show. Poor Chez was then dropped from her new role as a US judge after four days and was replaced by Nicole Scherzinger, leaving her to lick her wounds back in Blighty. (Pic: Bauer Griffin)
