Pete Waterman has announced that the live gig will be held at London's O2 Arena on Friday, December 21.
The show - to mark the 25th anniversary of Waterman's record label PWL - was originally scheduled to be held in Hyde Park back in July, but was axed due to poor weather conditions.
"We were devastated when Hyde Park's Hit Factory Live had to be cancelled," Waterman told The Official Charts Company.
"The moment had passed, that was it. So I then decided that maybe we could do something indoors. My favourite time of year has always been Christmas, and we found out the O2 was available on December 21!"
The Hit Factory Live Christmas Cracker will also feature Bananarama, Dead Or Alive, Pepsi & Shirlie, Princess, Sinitta, Hazell Dean, Sonia, 2 Unlimited, Lonnie Gordon and Brother Beyond, with more special guests to be confirmed.
However, Kylie Minogue has yet to be confirmed as a performer at the event, after she was originally lined up to perform 'Especially for You' with Jason Donovan.
When asked if she may appear, Waterman said: "Everybody's on the bill that would have been on the bill at Hyde Park. As ever, I can't give away too many secrets.
"The thing with all these things is, you have to wait and see!"
