Alessandra Ambrosio, 43, shows off her phenomenal physique in skimpy black string bikini while frolicking on the beach in Brazil

Alessandra Ambrosio looked radiant in a teeny-tiny string bikini while playing on the beach on Monday.

The 43-year-old supermodel showed off her phenomenal body in a full black bikini top with barely-there gold straps and matching cheeky bottoms.

After taking a dip in the ocean, she turned the beach into her catwalk, showing off her washboard abs as the water trickled down her body.

The former Victoria’s Secret Angel, who was spotted enjoying a romantic getaway in Ibiza with handsome Alexander Smurfit earlier this month amid rumours that her relationship with Richard Lee was over, appeared to be thoroughly enjoying the sunny winter day in the southern Brazilian city of Florianópolis.

She let her dark brown locks, which were wet from the water, hang loose and put on narrow sunglasses to protect her eyes from the sun.

Under her chic sunglasses, she appeared to be wearing no makeup, showing off her natural, bare beauty during her relaxing stay at the coast.

When she wasn’t swimming, she wore a cream and black bandana-inspired cover-up over her bikini.

She also donned a wide-brimmed straw hat and carried a fresh coconut as a drink for her day at the beach.

The Brazilian bombshell also wore layers of beads and dazzling tennis bracelets.

To accentuate the gold details of her bikini, she wore a pair of large, round earrings.

The model also wore a gold ring on her ring finger and one on the middle finger of her other hand.

She showed off her blonde hair and tanned skin during what appeared to be her only day at the beach.

She appeared to be getting ready to take a dive and a dive. Ambrosio made waves as she waded into deeper water.

The mother of two appeared to enjoy a solo getaway during her trip to her native Brazil.

Her daughter Anja, 15, and her 11-year-old son Noah, both of whom she shares with her ex, Jamie Mazur, were not with her.

Ambrosio was in a relationship with the entrepreneur for ten years, but they broke up in 2018.

From 2018 to 2020, she was also in a relationship with Nicol Oddi.

In 2021, Ambrosio began dating Richard Lee.

Ambrosio and Lee, a fellow model, dated for two years before splitting in September 2023.

A source told DailyMail.com at the time that they had taken a “break” and it was “unlikely” they would get back together.

The following month, the couple was spotted out in public enjoying a stroll through New York City, displaying their affection for one another, briefly sparking speculation that their romance had been rekindled.

The status of their relationship is currently unknown as they have not been seen together since then.

Ambrosio has recently been reported to be in a romance with Alexander Smurfit, the 39-year-old son of Irish businessman and multimillionaire Sir Michael Smurfit.

In early July, the couple were spotted on a romantic getaway to Ibiza, where they both showed off their toned figures.
