Karanikolaou also shared an overhead view of herself cooling off in the pool, chugging her drink as she floated in the water. In another snap, she offered fans a faceless close-up of her body, putting her figure front and center.

At one point, she got playful — sticking her tongue out, balancing the Celsius can on her head and dipping low into the pool while flaunting her cleavage.

Karanikolaou’s pool day comes not long after she opened up about her changing look.

On her “Better Half” podcast in May, she told co-host Alexis Fleischer, “Getting my t------ done tomorrow! Getting my a-- reduced in a month.”

The model has always been candid about her plastic surgery journey. She first had a b----- augmentation in 2017 with Beverly Hills surgeon Dr. Ashkan Ghavami.

At the time, she explained to Harper’s Bazaar that it wasn’t just about looks.

“I used to have the cutest, perkiest b----- when I was young,” she admitted. “Someone had told me that if you wear an underwire bra it makes your b---- sag. I had cute b---- so I would never wear a bra. Over time, I found out that whoever told me that was completely wrong.”

“If I was insecure, I wouldn’t have showed it,” she added. “I wanted to show people that there’s nothing to be ashamed of — that it’s so common for girls to have this issue and you can do something to fix it.”

By 2022, though, her perspective shifted.

“Over the past couple years, I've made my implants smaller, I've tried to make everything smaller because I just like the more natural look,” she revealed on the “Call Her Daddy” podcast. “You grow up, you change, you learn things, you see things differently.”

She added, “I wanted to feel good about my t-----, so I did them. Other things too. So that's that."

More recently, she admitted one of her biggest regrets — her Brazilian B--- Lift.

On her podcast, she confessed, “I think it's not a secret or something that I can physically hide at this point. Yes, I have a BBL. I moved fat around to my b---."

Now, she’s working to reverse it.

“It is something that I regret and that I've been actively trying to fix for so long,” she said. “I literally have another surgery like in a few weeks to try and reduce the size of it even more.”

Looking back, Karanikolaou admitted why she made the decision in the first place. “I felt just the pressure of the world that we live in and the trend of the times,” she added.
