Kaia Gerber showcased her incredible model frame while enjoying a holiday to Cabo, Mexico - without boyfriend Austin Butler.

Kaia, 23, flaunted her toned abs and her pert derriere in a tiny blue thong bikini by Sommer Swim while on her beach vacation on Monday, January 1st.

Kaia flashed a smile during her splash session in the ocean - amid mounting rumors that her and Austin, 33, have split. 

Her solo trip to Mexico without Austin is unusual - as the Elvis actor has been snapped on holiday with her there on multiple occasions.

Kaia and Austin - who share a 10-year age difference - haven't been pictured together since their date night on October 5th in New York City.

The couple initially sparked dating rumors in December of 2021, and they made the relationship official when they celebrated Valentine's Day together in February 2022. 

The daughter of legendary model Cindy Crawford frolicked in the ocean, joined by two pals.
