Girls Aloud have hinted that they might do something a bit wild on their upcoming reunion tour.

The popular group revealed recently that they were due to release a greatest hits album and tour the UK and Ireland next year to celebrate their 10th anniversary.

Kimberley Walsh told Capital FM that they might go a little left-field on the tour and do "something crazy". Speaking about the 2013 jaunt, Walsh said:

"We're going to do another tour, so we can maybe come from the ceiling again or maybe come from the side of the arena or do something crazy, we've still to achieve that."

The 2013 tour will open in Newcastle on February 21 before ending up in Liverpool on March 20.

Tickets for the gigs are due to go on sale at 9am UK time today (October 26).
