Sir Bruce Forsyth and Tess Daly present the exciting live final from Blackpool's Tower Ballroom. This is the last chance for the couples to impress, as the viewer votes decide who is crowned the Strictly Come Dancing champion 2011, with the glitterball trophy up for grabs. As well as a performance from the brilliant Jessie J, all the couples from the cast of Strictly 2011 also take part in a very special group number.
