"Due to unforeseen family circumstances, I deeply regret that I am having to cancel all of my upcoming work projects", a statement on his website reads.
The news includes the cancellation of the anticipated Dance for Life and his other live commitments and television shows in the pipeline.
Fans everywhere are left heartbroken as Peter Key reveals that he has been forced to cancel the entirety of his live United Kingdom tour due to undisclosed family matters.
'I've always endeavoured to project my family's privacy from the media. I hope that the media and public will continue to respect our privacy at this time.
Kay was due to perform more than 100 shows from April 2018 to March 2019, in venues including Manchester, Liverpool, Leeds, Sheffield and Newcastle. "Once again I'm very sorry".
The tour was due to start in April 2018 in Birmingham and visits all major United Kingdom and Ireland arenas right through to 2019.
While some fans were upset that there wasn't a clearer explanation as to why the tour had been cancelled, the majority of Peter's supporters fully understood his decision.
Touts sold on tickets for up to to £550 after the 2018 portion of the tour swiftly sold out last month.
Peter now holds the record for the biggest-selling comedy tour of all time after playing to 1.2 million people in 2010.
In his statement today, Kay also added that customers would be refunded from the "original point of purchase and any specific ticket queries should be directed to them".
