The Christmas blaze had started due to some festive candles in the family living room, with husband Ozzy's "arm and half his hair" on fire while the assistant slept in the guest house.

She told the other panelists: "I thought, right, where is that assistant? So I go into the guest house, and he’s like: 'Is everything alright?' and I’m like: 'No, the house is on fire, get out and help, go in and get the paintings out'.

"And I said: 'You must go in and find the dogs.'"

"He said: 'I think I’m going to have damaged lungs'. I mean, please.

"So then I just said: 'If you don't think that's funny, do you think this is funny? You're fired."

Another added: "Well @MrsSOsbourne has just ousted herself as a horrible person on #WILTY.

"A PA saves your dogs from your burning house only to rip their oxygen mask and send them in to save your paintings.

"Then fire them for not finding the situation funny. I hope they sue for everything!"

A third said: "Normally quite like watching @WILTY_TV but the callous attitude of @MrsSOsbourne is just too much and the fact everyone else found it funny leaves me worried about the morality of the audience and other panel members."
