Gisele Bündchen’s relationship with her rumored boyfriend is reportedly heating up.

The 43-year-old supermodel was reportedly spotted hanging out with her jiu-jitsu instructor Joaquim Valente on Valentine’s Day, when they were seen kissing in her Miami neighborhood, sources told Page Six on Thursday.

‘They’re deeply in love,’ an insider said of Bündchen and Valente, though she has previously deflected when asked about rumors of their romance. DailyMail.com has reached out to representatives for Bündchen for comment.

The insider also claimed that the two have stayed together regularly in the wake of Gisele’s divorce from NFL superstar Tom Brady, which was announced in October of 2022.

Last month, the legendary beauty told Harper’s Bazaar that she originally took her children to Valente’s studio in hopes that they could learn some self-defense skills, though she soon wanted lessons of her own.

The rumors of a relationship only intensified after Joaquim was spotted on multiple trips Gisele took with her children to Costa Rica, as well as back to Brazil, where both hail from.

However, another source tried to tamp down on the ‘love’ talk, though they also claimed that Gisele and Joaquim were seeing each other.

‘[They’ve been] discreetly been seeing each other since the summer,’ the source said.

However, she was rumored to be dating the martial arts instructor even earlier than that, as she was asked about the rumors in a March 2023 Vanity Fair profile.

‘I think, at this point, unfortunately, because I’m divorced, I’m sure that they’re going to try to attach me to anything,’ she said of the rumors, before lavishing Joaquim and his brothers Pedro and Gui, who run the Valente Brothers Jiu-Jitsu studio with him that she attends.

‘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,’ she said. ‘He’s our teacher and, most importantly, he’s a person that I admire and that I trust. It’s so good to have that kind of energy, to have my kids around that type of energy.’

The fact that Valente has been seen — and photographed — doing much more with Bündchen than just practicing jiu-jitsu — including paddle boarding and going horse riding with the family during a trip to Costa Rica — has led her fans to think the two are romantically entwined.

After Gisele and the martial artist were seen on a Costa Rica trip just weeks after her divorce from Tom — who has been seen spending time with the model Irina Shayk in recent months — a source claimed to People that there was nothing to see.

The insider said that Joaquim had been seen going to Gisele’s house multiple times, but another source downplayed talk of ‘love’ but added that they’ve ‘discreetly been seeing each other since the summer’

‘[Joaquim] and his two brothers are Gisele and the kids’ martial arts teachers,’ they claimed. ‘They are not dating.’

However, Gisele and Joaquim are also said to have become ’emotionally involved’ over the years since they first met.

Gisele was in New York City on Monday night to celebrate her second campaign with the denim label Frame in New York City for its Fashion Week.

She jetted back to Miami and was seen there on Tuesday, the day before Valentine’s Day, as she took her German Shepherd for a walk.
