For the high profile occasion, the industry veteran’s chocolate-coloured locks were styled in a slicked back wet look and her makeup glowed under the lights.

The statuesque runway star finished the look with a pair of bright red heels and accessorised with gold earrings.

It comes after Alessandra enjoyed a romantic date night with her boyfriend, jewellery designer Buck Palmer in Rio de Janeiro last month.

Visiting her native Brazil, the couple stepped out for a dinner date at Spicy Fish and were all smiles as they stepped out in laid-back looks while strolling through the city a day ago — coordinated in all-black outfits.

Looking equal parts chic and Sєxy, Alessandra modelled a one-shoulder, midi dress with a scalloped trim at the top, an open back and a drop-hem, pleated skirt featuring a leg-baring slit.

She paired the slinky dress with metallic gold heels with double straps and a raffia clutch with matching hardware. 

The Victoria’s Secret Angel was also carrying a black-and-white, paisley-printed shawl in one hand while she hooked her arm with her boyfriend’s while entering and exiting the restaurant. 

The Brazilian bombshell looked stunning with her hair styled in messy, tousled beach waves.

She looked perfectly sun-kissed and flushed in a light, bronzed makeup look paired with a rosy pink lip.

At her side, her boyfriend — who Alessandra was dating for some time before going Instagram official with him late last year — donned an outfit that perfectly complemented hers.

He sported a black ʙuттon-down shirt with the sleeves rolled up and the top four ʙuттons undone to highlight his long, beaded necklace. 

He also wore matching beaded bracelets and silver rings to further accessorize his monochromatic outfit.

The designer sported black jeans and high-top sneakers with contrasting white laces during their dinner date. 

Their vacation comes about a month after they went Instagram official when Ambrosio declared her love for her new boyfriend in a gushing birthday tribute in December

The couple put on an affectionate display at the restaurant and seemingly couldn’t keep their hands off of each other as they wrapped their arms around each other.
