It's not just Will! Remember all these other celebs who dropped out of reality shows?
We're still pretty shocked about singer Will Young's decision to leave Strictly Come Dancing on Tuesday - but he isn't the first celeb to suddenly drop out of a reality TV show.
The Pop Idol winner, 37, said the mysterious move was due to "personal reasons", while his fellow contestants tweeted how sad they were to see him go.
But while the details of his departure are kept private, here are some of the reality show exits that we know a little more about...
1. Zara Holland - Love Island
The former Miss Great Britain left ITV2´s show in June after hearing that her mother had fallen ill. The move came soon after the 20-year-old model, from North Ferriby in Yorkshire, was stripped of her Miss GB title after she was filmed having sex on the show.
2. David Gest - Celebrity Big Brother
The American comedian announced his departure from the CBB house at the beginning of the year for "medical reasons". He was found dead in April at a luxury London hotel, aged 62.
3. Brian Belo - Big Brother
Last year, the former BB winner returned to the house, only to quit days later following arguments with fellow contestant Helen Wood. He made a dramatic exit by physically climbing out of the building.
4. Spencer Matthews - I'm A Celebrity... Get Me Out Of Here!
The former Made In Chelsea star last year dropped out of the gruelling jungle-based competition after admitting taking "steroid-based medication". The 27-year-old said he took the pills to bulk up and "look good in the shower".
5. Everyone else from I'm A Celeb...
Other big names to leave the jungle throughout the show's history include The Only Way Is Essex star Gemma Collins in 2014 and actor Craig Charles, following the death of his brother.
Katie Price quit the show nine days after joining for a second time in 2009 and, in 2003, EastEnders actress Danniella Westbrook left the show's second series twice in one day after giving an emotional video message to producers.
