This cheeky gender reveal is the grossest yet.

Professional prankster Paige Ginn held nothing back as she revealed the sex of her unborn baby — with a single fart.

The social media star got naked from the waist down for the announcement, showing a putrid plume of blue powder coming from her backside as she breaks wind. The video then pans to a trio of her pals cheering in the background.

Ginn, best known for her outrageous trip-and-fall stunts in public, posted the vile video for her 279,000 followers on Instagram.

But not everyone was tickled pink.

“Are you serious? This is discusting [sic] I can smell that through my phone,” one person commented.

Ginn’s gag-inducing stunt is the latest in a series of gender reveals gone wrong — horribly wrong.

In Iowa last month, a 56-year-old woman was killed by a flying piece of debris during one expecting couple’s explosive reveal.

Meanwhile, the release of 350 gallons of pink water caused a plane to stall — and crash — during a party in Texas in September.

Another explosive gender-reveal party sparked a massive wildfire in Arizona in 2017 that burned more than 45,000 acres and caused more than $8 million worth of damage.

Dennis Dickey, 37, of Tuscon, pleaded guilty to igniting the so-called Sawmill fire by shooting a rifle at a target containing the highly explosive substance Tannerite.
