Newcomer Darcey Bussell adds some sparkle to the Strictly Come Dancing panel as she joins her fellow judges for a spin round the floor - in a mirrored, glitterball-style dress.
All four judges will be seen dancing together in a new trailer as a taster for the forthcoming series in which Bussell replaces Alesha Dixon, who is now a judge on Britain's Got Talent.
Len Goodman, Craig Revel Horwood and Bruno Tonioli battle over who can perform the slinkiest moves as they vie for a turn with their new colleague in the show teaser.
The quartet filmed the routine, choreographed by Revel Horwood, at a country retreat and it is the first time since the launch of Strictly that all the judges have been seen dancing together.
The series returns to BBC One on September 15 when viewers will see the contestants team up with their partners for the first time.
Contestants include former children's TV presenter Johnny Ball - the oldest-ever entrant at 74 - and former England cricket captain Michael Vaughan. Others rumoured to be taking part are Girls Aloud and Jerry Hall..
