Alessandra Ambrosio rocks red string bikini to celebrate Labor Day poolside at her Santa Monica home

GAL Floripa co-founder Alessandra Ambrósio enjoyed an icy bloody Mary cocktail while celebrating Labor Day poolside at her Santa Monica home on Monday.

The 41-year-old CAA Model – who boasts 18.9M social media followers – showcased her pert posterior in a red string bikini on Instagram.

Alessandra shielded her face from the sun by wearing a $370 Ruslan Baginskiy ‘Monogram-Embellished Fedora Hat.’

Ambrósio covered up her phenomenal 5ft9in figure with a $169 Spell ‘Tyler “Chilli Tropicana” Short Robe’ on the holiday honoring the American labor movement.

The Brazilian bombshell – who moved to the States at age 15 – officially became a citizen after visiting the US Citizenship and Immigration Services federal building in September 2020.

Missing from Alessandra’s slideshow was her boyfriend since December 14, 2020 – Wilhelmina Model Richard Lee.

The Utah native – who’s in his 40s – marked Ambrósio’s first public romance since ending her two-year relationship with Alanui co-designer Nicoló Oddi in the winter of 2020.
