Alessandra Ambrosio flaunts her flat midriff in bikini as she holds hands with boyfriend Buck Palmer in Brazil

Alessandra Ambrosio showcased her body in a bikini while enjoying another beach day in her home country of Brazil - amid the devastating wildfires in Los Angeles.

The 43-year-old supermodel showcased her flat midriff and her pert derriere in her colorful 1960s inspired two-piece.

The beautiful Brazilian cover girl wowed in the swimsuit, which consisted of a one-shoulder yellow, purple and white sixties inspired pattern, and matching bottoms.

Alessandra held hands with her Australian jewelry designer boyfriend Buck Palmer during their beach day at the famous Ipanema Beach in Rio de Janeiro.

The model wore vintage inspired sunglasses and several bracelets, opting to go makeup free and leaving her brunette locks loose in waves.

Alessandra, who currently lives in the Los Angeles-neighborhood of Santa Monica, was seen arriving at the beach sporting a matching sheer cover up for a fashionable arrival.

Alessandra has been in Brazil for weeks - and even celebrated the New Year's there with her boyfriend. 

Their sighting in Brazil comes a month after they confirmed their romance by holding hands in Miami, Florida during Art Basel.

Two weeks ago, Alessandra let Buck borrow her phone to film her swimming across the ocean from a small island.

He provided commentary as she made her way across the water to him.

She shared another snap that showed that she 'made it' across to the other side.

Alessandra also bravely jumped off the rocks into the water - after Buck gave her support and encouragement that she could in fact do it.

The stunner also took a snap of Buck washing his face in the ocean, captioned it: 'My love in his natural habitat.'

Last month, the lovebirds shared kisses at the beach in cute snaps, which she posted to her Instagram page.

Alessandra shares two children with ex-partner Jamie Mazur: daughter Anja, 16, and son Noah, 12.

She lives in Santa Monica - a Los Angeles neighborhood; she resides in a home build in 1920, according to an Architectural Digest cover story she did in 2018. 

The LA wildfires have been ongoing in Los Angeles County since Tuesday.

Ten people have since died, with over 100,000 people evacuated in the affected areas, CNN reported.

According to the outlet, 10,000 properties have been destroyed - as four wildfires are still ongoing in the county.

Neighborhoods have been flattened due to the Palisades Fire - in the Pacific Palisades - as well as the Eaton Fire - in Altadena.
