There are fears Bruce Forsyth could have to miss tonight's Strictly Come Dancing semi-finals as he has been struck down by an illness.
The veteran TV presenter pulled out of rehearsals for the show this week, saying that he was suffering from a cold.
The 82-year-old may now miss tonight's show and Claudia Winkleman, who already presents the Sunday edition of the show, has been drafted in to learn Brucie's lines in case he can't make it.
A source from the show told The Mirror: "Bruce had to go home, he has flu-type symptoms and wasn't in a good way.
Claudia has been rehearsing his lines in case he can't make it out of his bed. It really is touch and go."
"The most important thing is that he gets himself well, especially as the final is next week. We would hate him to miss that. Knowing Bruce he'll have no intention of missing such a key show as the semi-final."
If Bruce feels ill today it is thought he will seek medical attention, before deciding if he should carry on with this evening's filming.
It would not be the first time this series that Bruce has missed out on hosting the show, as he took a break earlier in the run and was replaced by Claudia.
This weekend's shows will decide who makes it through to next week's final, with former Emmerdale actress Lisa Riley currently the favourite to go home as she is apparently struggling to learn the choreography for her two dances.
