Julia is extremely confident her man beats Molly Mae's boyfriend in their high-profile boxing bout next month.
And she's hoping to strike a bet with the Love Island star ahead of Paul vs. Fury on December 18.
But Molly-Mae hasn't responded, with Julia suggesting an alternative suggestion.
Speaking to TMZ Sports, the American bombshell said: "I tried having a bet.
"She didn't respond. Molly's not too confident in her man.
"Molly, let's make a bet. How confident are you in Tommy? Let's see."
Asked if she would get in the ring with Molly-Mae, Julia replied: "We could mud wrestle."
Julia has been vocal on social media since Paul announced his bout with Fury.
'The Problem Child' is confident ahead of his fifth bout and even compared himself to the likes of Muhammad Ali, Mike Tyson and Floyd Mayweather.
"It was my first real test that I passed. A UFC Champion who dominated the UFC with his big overhand right," he said at a pre-fight presser.
"He hit me with a shot in the fourth round that was nothing. I ate it very easily and kept moving.
"I found a way to win and passed my first test in my fourth professional fight.
"Nobody from Muhammad Ali to Mike Tyson to Floyd Mayweather was testing themselves as much as I was in my fourth fight.
"I learned a lot about myself and what I'm capable of and performing under pressure.
"I look forward to bringing that experience to my next fight."
