She’s a bachelorette babe.

Brittany Mahomes showed off some skin in a bold black swimsuit as she celebrated her friend Mallory Moss’ bachelorette party in Mexico over the weekend — and this Sports Illustrated Swimsuit model definitely knows how to turn up the heat.

The 28-year-old mom of two — who is married to Kansas City Chiefs quarterback Patrick Mahomes — posted a series of Instagram photos of herself posing on a boat on Saturday, showing off her toned abs in a $380 Louisa Ballou one-piece.

The high-cut suit featured plenty of cutouts.

The black bathing suit featured a halter neck and gold ring detail at the bustline and hip, with the fabric forming several cutouts that bared the fitness trainer’s toned abs.

While she didn’t give fans a back view of the suit, the style showed off plenty of booty with its minimal coverage bottom.

She wore her blond hair down for the party, accessorizing with square-shaped sunglasses and multiple bracelets on each wrist.

While some football fans filled her comments section with hateful remarks, plenty of followers loved the look, like one who wrote, “Well I know why she was a sports illustrated swimsuit model this year!!! HOT!!”

“If I looked like this I would be in a bathing suit all day everyday 🔥🔥🔥” another Instagram user added.

“Beautiful. So so sick of the jealous haters on your page. Jealousy never looked good on anyone. We love a high school sweethearts story. ❤” a third fan wrote.

Brittany made her Sports Illustrated debut in a series of sizzling red swimsuits this month, including another cutout one-piece ($660 $396), this time from Mugler.

And along with her new modeling gig and Mexican vacation, she’s had plenty of other fun celebrations recently, with her quarterback husband winning his third Super Bowl since 2020.
