Gymnast Olivia Dunne In Her Tight Leather Dress Turns A 'Lil Older'

Olivia Dunne turns 20!

The college gymnast stunned her 6.1 million TikTok followers with a hot birthday post on her page. In the new share, posted on October 1, Dunne uploaded a video in which she flaunted her incredibly toned figure.

The LSU athlete bid farewell to her teenage years and welcomed her twenties by rocking a sexy black dress. Its leather material clung to her every curve. The garb had a low-cut neckline that was quite daring and revealed her cleavage through the cut-out in the center. Its thin straps clung over her shoulders, leaving her toned shoulders and arms bare.

The backless design left plenty of skin exposed, while the short length of the piece showcased her lean legs. Dunne completed her outfit with a pair of high-heeled, sparkly boots. The stunner clearly felt comfortable in the ensemble as she did a TikTok post while clad in it.

Dunne chose the perfect audio for the clip as she lip-synced 50 Cent's "In Da Club."

While showing off her attire, Dunne sings the line, "Go, shorty. It's your birthday. We gon' party like it′s your birthday. We gon' sip Bacardi like it's your birthday. And you know we don't give a f--k it's not your birthday."

For the special occasion, the social media sensation wore her blond hair in a center part and styled it in soft curls. She let the long strands cascade over her shoulders and back. In terms of accessories, Dunne settled for sparkly, dangling earrings and two gold bangles worn on each wrist. Her makeup included sculpted brows, shimmering eyeshadow, glowing highlighter, pink blush, and lipstick.

Dunne's fans wasted no time showing the post some love. The video garnered more than 2 million views and upward of 300,000 likes. Her supporters also flocked to the comments section to leave over 3,200 messages for the birthday girl.

"Gorggg and I ain't trynna get your bathwater like the other people, I just think you are really pretty," one wrote.

"Girl you got everything popping 😍 ✨️Beautiful 🎶 🎵 ✅️😍 🤩 Outfit 🔥 Your hair is shining!" gushed another user.

"Amazing at 20 and she probably already has more money than I do," added the third commenter.

Dunne also shared some pics featuring her outfit on her Instagram page. She struck several poses -- showing some angles to the camera.

"Rip my teenage years #20 🥂" Dunne captioned the update.

Dunne has been doing gymnastics since she was a child. Currently, she's one of the top earners in college sports, thanks to her social media fame.

The Louisiana State star has over six million followers on TikTok and more than two million on Instagram.

When the NCAA rules were changed in June 2021, with college athletes allowed to profit off their image and name, Dunne signed up with a talent agency WME Sports. She also landed a sponsorship deal with an activewear brand, as reported by The Sun.

"I just want to be a role model to young girls," Dunne, who became a millionaire at 18, told New York Post. "I want to set a good example, and I want to send out a message that we're more than just our sport. That's very important to me."
