It was confirmed that Will had quit Strictly Come Dancing back in October last year, pulling out after four weeks into the live shows.
A spokesperson for the BBC announced 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."
Will said in his own statement: "To be a part of Strictly has been a long time ambition of mine. As a performer, a viewer, and a fan of the show, to dance as a contestant was an experience I always hoped for.
"I have made some great friends, and am in awe of their performances week in, week out. I have found a creative partnership with Karen that has been the most wonderful thing to experience."
He continued: "Unfortunately, I am leaving the show for personal reasons. I leave with joy in my heart that I have been able to take part in one of the most loved shows on British television."
Speaking on ITV's Good Morning Britain today, Will's pro partner Karen confessed she still wasn't sure why he left.
"I had to put a tough face on that one, I'm not going to lie. I mean, he had his reasons. I'm still not 100% sure why," she explained.
Strictly winner Ore Oduba, who was on the show to plug the upcoming Strictly tour, added: "It was a surprise to all of us."
According to The Sun newspaper, Will was given the chance to return for Strictly's final last month.
"Will was asked if he wanted to come back for the final show, but was quick to turn down the chance," a source told the tabloid. "He put a real spanner in the works for the whole show and meant that despite there usually being four finalists there was only three this year.
"It wasn’t like he sustained an injury or gave a proper explanation so the execs were pretty angry with his behaviour and felt like he had let the show down."
Strictly Come Dancing will return for a brand new series on BBC One later this year.
