The 37-year-old “Transformers” actress showed off her sᴀssy style in a post she captioned “a mother,” wearing a high-necked Poster Girl sleeveless top ($573) that laced up the front, revealing plenty of cleavage.

She took the pantsless trend for a spin by pairing the black canvas style — which featured a crystal-covered buckle at the neck — with matching faded black ruffle-trimmed H๏τ pants ($273) that zipped up the front.

Fox wore a black leather jacket off her shoulders, teaming the look with over-the-knee black cowboy-style boots ($1,179 $826) with red detail by Sonora.

The “Teenage Mutant Ninja Turtles” star wore her freshly dyed pink hair down in a wet look for the bash, which was held at XS Nightclub in the Wynn Las Vegas resort.

She accessorized with another Poster Girl creation, carrying a tan handbag ($509) from the brand featuring pink snakeskin detail, silver studs and a crystal-covered buckle.

Fox kept the pink theme going with her makeup, wearing shimmering eyeshadow and dark pink lip liner with a lighter rose shade of lipstick.

She joined stars like Taylor Swift, Travis Kelce, Jason Kelce and Brittany and Patrick Mahomes at the bash, where the Kansas City Chiefs celebrated their win against the San Francisco 49ers.

As for her new look, Fox debuted her new pink hair — a look she also rocked alongside fiancé Machine Gun Kelly in 2022 — at a Grammy watch party last week along with a fresh tattoo sleeve.

The on-again couple seemed to be back together at a Super Bowl party in Sin City on Friday, though they’re keeping their relationship more hidden than in the past.

Here’s to everything coming up rosy for this pair in 2024.
