"Have a cracker of a #weekend everyone #sunsoutbunsout," he captioned the video.
But as his fans cheekily pointed out, the 35-year-old hadn't taken into account the fact he has a reflective glass pool fence.
Naturally, this sent the internet into a spin, with many admitting they were zooming in to sneak a peak of his "johnson".
"Zooms in on the reflection," one person teased.
"Bronson and the johnson," another said.
"The reflection though," another commented, while someone else said: "Stares at the shadow for clues."
Some of his co-stars also chipped in, with Cyrell Paule, teasing him for the naughty video.
"I bet ur neighbours love u," she posted.
While Mike Gunner said: "Be careful not to poke yourself in the eye."
Others confessed they would do anything to be on the other side of the fence.
"Wish I was one of your neighbours," one fan wrote.
"We need neighbours like this," someone else chipped in.
However, his impressive physique is definitely not a surprise to followers, as he regularly shares shirtless snaps on his social media platform.
Despite accidentally baring all to his fans, Bronson appears to be doing well since his marriage with fiery Ines Basic went down the pan on TV.
Thankfully, the super strong Bronson has moved on, recently revealing his new girlfriend pole, dancer Melissa Dobson.
