It was confirmed that Will had quit Strictly Come Dancing back in October, pulling out after four weeks.
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."
According to The Sun newspaper, Will was invited to return to the show's final along with all of the other celebs from this year's line up.
However he has "politely declined the offer", according to show insiders.
A source told The Sun newspaper: “Even though Will wasn’t technically eliminated, he was still asked to be part of the group dance during this year’s final episode.
"It’s a great routine which welcomes back all of this year’s ‘Class of 2016’ for one final celebration. Unfortunately, Will has politely declined the offer.”
A spokesperson for the BBC commented: “Details about the final will be announced in due course.”
Earlier this year, Will's former pro partner Karen Clifton spoke out about the TRUTH behind his exit.
Karen jumped to defend Will against various reports including that the pair 'squabbled' backstage and he had 'failed to turn up' to training sessions.
"I've spoken to him a couple of times [since he left] and we text. He's doing well. We try to keep in touch as much as we can," Karen said.
Asked if there really had been any clashes between her and Will in training, Karen declared: "Absolutely not.
"We had the best time and I love him to pieces. He was great and we always had a good time. We had the most amazing three weeks on Strictly that I'm always going to remember, and we had some great dances that will be in the history of Strictly Come Dancing."
Karen also denied claims that Will had not been putting enough effort in and had failed to turn up to rehearsals.
She explained: "He was a hard worker. He always came in and gave 150 percent. I don't think he even thought for a second that it wasn't going to be hard. I couldn't have asked for a better student."
Strictly Come Dancing continues Saturday and Sunday nights on BBC One.
