Over three weeks, 18 celebrity acts have put their pride and dignity aside and danced their socks off in the name of charity. Those 18 acts have been whittled down to six finalists by a viewers' vote. Six finalists now dance again to determine who is crowned Let's Dance Champion 2010.
The nation was arrested by the sight of Debra Stephenson's Smooth Criminal; they fought for the love of Rufus Hound with his tribute to Cheryl Cole; GMTV's Kate Garraway and Richard Arnold hand-jived; and Katy Brand did it for single ladies everywhere with her version of Beyonce's classic track. These four acts are joined by two others in the grand final.
There's a special performance by the cast of hit West End musical Billy Elliot, and panellists casting judgement over the celebrity dancers include 2009's champion Robert Webb, impressionist Jon Culshaw and comedian Jack Dee.
