The 18th series of Strictly Come Dancing is well underway and this year we've seen four new professional dancers join the popular BBC One show. Over the years, viewers have watched 64 professional dancers take to the Strictly dance floor and there's now only Anton Du Beke left from the first series, but he is part of the judging panel rather than the competition. There's been married couples take part in the show, such as James and Ola Jordan and Lilia Kopylova and Darren Bennett, as well as some who even fell for their celebrity partners during their time on Strictly.
