Kylie Minogue is due to reunite with Jason Donovan in December.
Pop producer Pete Waterman had planned to reunite the pair at his outdoor Hit Factory concert, but it was cancelled in July because of safety fears due to heavy rainfall and mud in Hyde Park.
However he is now hoping to get the former on and off-screen couple together at the end of the year to perform in at least one show.
Waterman said: "We are going to do it again at Christmas. We are going to do two nights at the 02 or at least one night, we've just got to confirm one artist who is due to go home for Christmas, I'll give you a clue there."
He added: "I just have to convince that artist to stay here until at least Christmas Eve and we can do it all the way we want to."
Donovan and Minogue - who were briefly a couple and co-starred in Australian soap opera Neighbours - didn't rule out performing their song Especially For You at a later date when the recent incident occurred.
The 44-year-old singer-and-actor tweeted: "Well... you never know, I'm sure we'll get another chance!! Fingers crossed."
