Gisele Bundchen shows off her sculpted figure while paddleboarding with her ... trends now

Gisele Bundchen slipped into a cheeky thong bikini for a paddle boarding date with jiu jitsu Joaquim Valente, in Miami on Saturday, fueling rumors of a hot new romance.

The 42-year-old flashed a wide smile and donned a form-revealing outlet as she pushed herself along the city's waterways as she spent time with the fitness instructor.

The supermodel, who recently auctioned off one of her Stella McCartney gowns, opted for a black bikini top that exposed her toned midsection and chiseled arms.

Bundchen also donned a matching bottom that highlighted her impressively sculpted legs.

The former Victoria's Secret Angel accessorized with a pair of sunglasses that gave her look a bit of extra darkness.

Valente opted for a pair of olive green trunks and a trucker cap during the paddleboarding trip.

Bundchen and the jiu-jitsu instructor were initially linked in November of last year, when they accompanied one another during a trip to Costa Rica.

However Gisele, who has two children Benjamin, 13, and Vivian, 10, with Brady, has previously played down rumors of a romance with Valente.

When asked about the status of her relationship with him, she told Vanity Fair's April issue: 'I think, at this point, unfortunately, because I'm divorced, I'm sure that they're going to try to attach me to anything.'

Still, Gisele was full of praise for Joaquim, who trains her and her children in the art of jiujitsu and has regularly been seen spending time with the fashion star and her kids during their frequent trips to his native Costa Rica.

Speaking about Joaquim and his two older brothers - alongside whom he runs a jiujitsu training center - the model said: 'They're awesome people. They have created this safe space.

'I'm so grateful to know all of them, because not only have they helped me and helped my kids, but they have become great friends, and Joaquim especially.'

Tom and Gisele finalized their divorce on October 28 last year and she described the split as the 'death of her dream' - while blasting rumors that she gave the football pro an ultimatum forcing him to choose their relationship over his sporting career.

In the Vanity Fair interview she described the speculation surrounding her split from Tom, 45, as 'very hurtful', while insisting that she has only ever 'wanted all his dreams to come true'.
