The founder/choreographer of Hot Gossip was Arlene Phillips (http://en.wikipedia.org/wiki/Arlene_Phillips#Hot_Gossip), who up until 2009 was one of the judges on the UK's Strictly Come Dancing (which spawned several Dancing With The Stars international offshoots), until being dropped, possibly for being too old and a woman, though the BBC denied that.

However, maybe someone at the Beeb saw this video* and decided that she was indeed no professional-level choreographer and had not earned the right to judge other people.
