Alessandra Ambrosio puts on a very cheeky display as she models a series of skimpy swimsuits in Hawaii

Alessandra Ambrosio declared she is ‘always on vacay’ with a magenta swimsuit on a Hawaii before putting on a cheeky display for Instagram on Friday.

The Brazilian model, 43, relaxed in the shallow water of a beach in Hawaii, pairing her costume with a blue baseball cap and gold necklaces.

Moving to the rocks opposite the beach, Alessandra revealed that her suit was thonged as she posed with her arms outstretched.

In another snap, the beauty, who once dated Cristiano Ronaldo, waded into the water, but this time she wore a off-white crochet thonged one-piece.

As Alessandra posed with two friends on the sand, she showed off the stunning detailing on the backless swimsuit.

Her friends ripped off their sarongs and the trio posed for another snap, this one knee-deep in the Pacific Ocean. 

In a floral pink swimming costume and wearing a pale pink crystal necklace, Alessandra enjoyed some frozen fruit. 

Making the most of her trip, Alessandra took a very close-up selfie in a large pair of clear goggles, hinting she was about to go snorkelling. 

As the sun began to set, Alessandra took a gorgeous close-up make-up free selfie with orange clouds in the background. 

In a different location, she sat cross-legged on a bench and wore a black dress and shirt, throwing up double peace signs.

A final post showed Alessandra and four friends looking cosy on the side of the road, greenery spreading behind them. 

Joining Alessandra in Hawaii is her mini-me daughter Anja, 15.

In a Wednesday Instagram post, Alessandra’s firstborn child — who will turn 16 on August 24 — joined her in a lagoon.
