The Spice Girls suffered a Girl Power Failure Sunday night when a number of ticket holders failed to turn up for their Las Vegas gig.

Despite their comeback tour supposedly being ‘sold-out,’ footage of the gig clearly shows that almost half of the seats in the Mandalay Arena auditorium were empty as the group took to the stage.

The fans may be turning their backs on the girls but at least the private box was full.

Victoria Beckham's co-WAG Coleen McLoughlin and defeated boxer Ricky Hatton joined David Beckham to cheer on Baby, Sporty, Ginger, Posh and Scary.
