During a conversation with Charlotte Crosby and Dale Thomas, the British reality star asked Rhonda what the Big Little Liars actress was like in person, with the 59-year-old randomly admitting that behind closed doors, Nicole is a completely different person.
"She was doing the movie, Australia. Do you know the movie, Australia? She used to complain about the blow flies and the cows mooing," said Rhonda who met the Oscar winner while she was in acting school.
After Dave asked whether she was a "flat out diva", Rhonda replied, "flat out!".
This isn't the first time an I'm A Celeb contestant has called Nicole out on her questionable behaviour. Last year, I'm A Celeb contestnat Kerry Armstrong said that while she was competing against Nicole for the Best Actress award at the AFI Awards, the Bombshell star was so enraged when she lost, she stormed out of the ceremony.
"We were so waiting for Moulin Rouge to win everything. So Nicole was all up getting ready and [presenter Russell Crowe] said Best Actress and he said my name," Kerry recalled.
Vince [Colosimo] or Anthony LaPaglia came up and said she had left the room."
