The 37-year-old is set to put her IBF female bantamweight title on the line against her rival on December 19 in San Francisco.
Bridges and Mathie are both known for putting on a show at their weigh-ins, as well as their skills in the ring.
Quizzed on social media if the weigh-in with Mathie would be “lit”, Bridges responded: “Lit is an understatement #BattleOfTheBoobs!”
Both stars produce content for OnlyFans on the side, but world championship glory will be the main focus in December.
Asked by one fan if they can avoid each other’s faces, however, Bridges joked: “Hahaha not sure I wanna pop a t***ie.”
Mathie, 36, then chimed in: “Would only be fair play after I’ve already exploded your right t*t.”
Bridges cheekily responded “You gotta land on it to do that babes,” before Mathie hit back: “You say that like they’re gonna be hard to miss.”
While fighting talk may take over in the coming months, Bridges is actually full of admiration for Mathie.
Chatting to talkSPORT, the Blonde Bomber admitted: “I love Avril, I think she’s great, honestly!
“She works really hard and I respect her for what she does, her hustle, her lifestyle and what she’s done.
“I think it will be a great fight and it will definitely be crowd pleasing. I think our weigh-ins will break the internet.”
Bridges was less complimentary when asked how she thinks the fight will go, adding: “I don’t really see it going past the first four or five rounds, obviously with me winning.
“She’s a tough Aussie, but so was Shannon O’Connell and I’m just getting better and better.
“So, it will be exciting if we have that fight and I would like to fight her and as she said we were in talks for a fight.
“I would like to give her that opportunity because I think she’s great and I think she deserves it.”
