The BBC confirmed this evening that the 'Jealousy' singer, who was partnered with Karen Clifton, has withdrawn for "personal reasons".
"Due to personal reasons, Will Young has decided to withdraw from Strictly Come Dancing," said a spokesperson for the broadcaster.
"The show fully respects his decision and wishes him all the best for the future."
Will released a lengthier statement, reading: "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. I will be eternally grateful to her for her direction, talent and guiding me through three wonderful dances that I will be able to show my grandkids in years to come."
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.
"I am so grateful to everyone who works on Strictly from the lighting designer to catering to the production team. Strictly truly is the most unique family and I thank them from the bottom of my heart."
The Beeb refused to comment further on the circumstances surrounding Will's exit. However, it is not thought to be linked to his clash with Len Goodman in Saturday's show.
When Will took issue with Len's criticism of his Salsa routine, which scored 31, the head judge told him to "turn up, keep up and shut up".
The Pop Idol winner previously scored 30 for his Tango, and 27 for his Jive.
