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.

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.

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.

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.

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.
