Olivia Culpo shimmered in a silver Poster Girl dress at her birthday bash.

Hopefully Olivia Culpo’s not planning to board a plane in her birthday dress.

The former Miss Universe celebrated turning 30 in Miami over the weekend, dressed in a backless metal mesh mini ($663) by celeb-loved label Poster Girl.

Culpo paired the shimmering style — which includes a low draped neckline and hip-high slit — with equally eye-catching René Caovilla heels ($1,410) with sparkling straps that snaked up her ankles.

On Sunday night, the star shared a series of snaps and videos from her big night on Instagram, including footage of herself pole dancing on a party bus, posing with a towering five-tiered cake and snuggling up to her boyfriend, Carolina Panthers running back Christian McCaffrey (who wore a Fendi logo shirt and dark denim).

“30th birthday! This milestone scared me but I have to say I feel so incredibly grateful for the people in my life, and for all of you,” Culpo captioned her post.

“Thank you for following my crazy journey through life and giving me an outlet to be myself. I don’t want this to be too long but I love you guys and thank you so so much for the bday wishes !!!!”

The social media superstar’s sexy style has landed her in hot water in the past; back in January, she was famously asked to “cover up” after arriving to catch a flight in a bralette and matching bike shorts, and had to borrow McCaffrey’s hoodie in order to board. (She later poked fun at the viral incident by posing in an even more revealing outfit on Instagram.)

And in March, she modeled a risqué cutout Mônot dress nearly identical to the one Kendall Jenner wore to a friend’s wedding in 2021, which many deemed “inappropriate” and “disrespectful” for the occasion.
