At least someone's smiling: Sarah Harding looks excited after Girls Aloud kick off countdown to reunion on Strictly

Following a three year hiatus, Girls Aloud are finally set to reunite next week for a special performance on Strictly Come Dancing.
After kicking off a 10-day countdown on the girl band's new Twitter page, bandmember Sarah Harding certainly looked excited as she left Scott's restaurant in Mayfair following a lunch date.
Meanwhile, her bandmates Nicola Roberts and Kimberley Walsh were also spotted out and about in London, although not looking quite so happy as Sarah.

Sarah, 30, looked glowing in a pair of PVC leggings, red suede boots, blouse and her favourite furry waistcoat as she beamed at photographers.
However, Kimberley looked rather stressed as she rushed to rehearsals for her second dance on Strictly with partner Pasha Kovalev.
Meanwhile, Nicola was seen leaving her London hotel in a black and cream ensemble as she went to a meeting.

On Tuesday, the new Girls Aloud Twitter page was launched, starting the 10 day countdown to their reunion on Strictly on Friday 19 October.
All of the band with Twitter - minus Sarah - retweeted their new group page as they whipped their fans up into excitement at their impending reunion.
Despite Cheryl having been a mentor for three seasons on the X Factor, she decided that Girls Aloud should make their grand return on the rival BBC show.
Girls Aloud, made up of Cheryl, Kimberley, Nicola, Sarah Harding and Nadine Coyle, have been on an extended hiatus since 2009, but planned to get back together later this year to celebrate 10 years in music.

While Cheryl has been a judge on X Factor and released three albums, both Nadine and Nicola have released one, Kimberley has been presenting TV and appearing in the theatre and Sarah has turned her hand to acting.
The group were formed in November 2002 after being chosen by judges Geri Halliwell, Pete Waterman and Louis Walsh on the ITV talent show from thousands of wannabe pop stars.
Their debut single Sound Of The Underground went straight to number one, with their debut album of the same name selling over 300,000 copies.

The five-piece have enjoyed three number one singles and a further 16 top 10 hits over their seven years in the charts.
Their last single release, Untouchable, was their lowest-charting single, reaching no.11 in UK charts in April 2009.
Their six albums have sold more than 1.8million copies in the UK, their most successful being their greatest hits disc The Sound Of Girls Aloud, which has been certified 3x platinum.
