Kaia Gerber showed off her incredible model figure while enjoying a vacation in Cabo, Mexico – without her boyfriend Austin Butler.

Kaia, 23, showed off her toned abs and pert derriere in a tiny blue thong bikini from Sommer Swim during her beach vacation on Monday, January 1.

Kaia flashed a smile as she splashed around in the ocean – amid rumors that she and 33-year-old Austin had split.

Her solo trip to Mexico without Austin is unusual – as the Elvis actor has been photographed there on vacation with her several times.

Kaia and Austin — who have a 10-year age difference between them — haven’t been pictured together since they met on Oct. 5 in New York City.

The couple first sparked dating rumors in December 2021 and made the relationship official when they celebrated Valentine’s Day together in February 2022.

The daughter of legendary model Cindy Crawford frolicked in the sea with two friends.

Kaia jogged into the ocean looking every bit the supermodel that she is.

Her two pals appeared to stay on the shore while she enjoyed a dip in the sea and was beaming from ear to ear.

The star arrived at the beach wearing a figure-hugging green minidress over her swimsuit and a baseball cap.

Rumors of a breakup have been circulating for months since Kaia and Austin were last seen in public.

The duo was spotted holding hands after a date night in the Big Apple on October 5.

In her latest outing in the photo, Kaia flashed her midriff in a fitted T-shirt with jeans.

Austin has been making solo red carpet appearances since their rumored split.

The duo was first linked in December 2021.

Since then, their relationship had only grown stronger.

Austin and Kaia made their red carpet debut at the 2022 Met Gala after just a few months of dating.

They hit the red carpet as a couple at several other events, including the Time 100 Gala in 2023, where they shared a PDA moment.

Additionally, they attended the Vanity Oscar Party in 2023 and the Bikeriders premiere in Austin in the same year.

Austin and Kaia dressed up as Edie Sedgwick and Andy Warhol for Halloween 2023 for a cute couple look.

They also attended his Dune: Part Two premiere afterparty in London together in February 2024.

Before Kaia, Austin was in a long-term relationship with Vanessa Hudgens for almost nine years – from September 2011 to January 2020.

Kaia previously dated Jacob Elordi and Pete Davidson.
