The 33-year-old rose to fame during the seventh series of the reality show, quickly becoming famous for her diva tantrums.
Now Nikki has hinted at a return to our screens.
Speaking to 5 News ahead of the launch of the latest series last night, Nikki said: "I'm not going in tonight but I would quite fancy doing I'm A Celeb before I go back in the house."
When pushed to reveal whether she would be joining the current housemates, Nikki replied: "I don't want to spoil any surprises."
BBBOTS host Rylan Clark previously suggested we could see some of our favourite housemates make a return this year.
He said: "We can also visit the past so they might wake up one morning and it be Big Brother 2007 or we go back two years and suddenly I'm a housemate again for a few days.
"Nikki Grahame, Makosi... What's to say they never actually left?"
But Nikki has suggested that, if she does enter the house this year, her tantrums might be a thing of the past.
She added: "I was a real crazy character, wasn’t I? But that was like ten years ago. I had a lot of nervous energy, I’ve mellowed.”
