Kerry Armstrong has thrown a spotlight on a brilliant Nicole Kidman diva moment.

Speaking to Fiona O'Loughlin and Jackie Gillies in the I'm A Celebrity Get Me Out Of Here camp, Armstrong revealed what happened on the night she beat Kidman to the Best Actress award at the AFI Awards.

It all began when Gillies, apparently through her psychic abilities, reverse predicted that she should have appeared alongside Kidman in her hit TV series Big Little Lies.

Armstrong replied she also would have been good in another Kidman star vehicle, Lion, then took a dig at the Oscar-winning actress.

"Have a rest buddy, have a rest," Armstrong said of Kidman's career renaissance.

But it was then things got really juicy as she began to recount the night Kidman was nominated for the best actress award for her turn in Baz Luhrmann's Moulin Rouge against Armstrong's appearance in the acclaimed Australian film Lantana.

"I say that as a joke but when we went up against each other for the AFI Awards it was Moulin Rouge against Lantana," Armstrong explained.

"We were so waiting for Moulin Rouge to win everything and then we won for Sea Change first."

Russell Crowe, who was at the peak of his fame back in 2001 for his turns in Gladiator and A Beautiful Mind, had deigned to appear at the AFI Awards that year to present the best actress award. He is also close to Kidman.

"Russell Crowe said I am here to announce best actress, there's four really wonderful ladies, I've got a bit bias going on, so I have come all this way to announce best actress," Armstrong said.

"Nicole was all up getting ready and he said best actress and he said my name."

According to Armstrong there was quite a bit of commotion in the corner of the room where Kidman was sitting, and she later found out the reason.

"Vince (Colosimo) or Anthony LaPaglia came up and said she had left the room," Armstrong said.

"I went up on stage (to collect the award) and Russell Crowe was visibly unimpressed, he was really unimpressed."

Kidman went on to earn an Academy Award nomination and to win a Golden Globe for her performance in Moulin Rouge, despite the AFI snub.
