It was confirmed that Will had quit Strictly Come Dancing last week in a surprise announcement.
A spokesperson for the BBC revealed at the time: "Due to personal reasons, Will Young has decided to withdraw from Strictly Come Dancing. The show fully respects his decision and wishes him all the best for the future."
In last Saturday's live show, hosts Tess Daly and Claudia Winkleman confirmed Will's exit and told cameras: "Will if you’re watching we love you and we wish you all the best."
Karen had been partnered up with Will and was backstage at rehearsals tonight where she spilled on what's been going on.
Chatting on It Takes Two, the dancer said: "I've been fine, it's been tough.
"I miss him very much but I wish him the best."
Karen added: "As long as we've ll got each other, everyone around has been very supportive and I just want to support everyone as much as possible."
The exact circumstances regarding Will's departure are still unknown but there were claims of clashes between him and Karen.
Will supposedly failed to show up to training with Karen after making her travel SIX HOURS to Cornwall.
The Daily Mirror reports that the incident came just before Will walked off the show for "personal reasons".
Strictly Come Dancing is back this Saturday and Sunday night on BBC One.
