Gisele Bundchen was spotted in Miami.

Gisele Bündchen secretly bought an $11.5 million Miami Beach mansion directly across the creek from Tom Brady’s pad, Page Six has exclusively learned.

The supermodel splurged on a stunning five-bedroom, 6,600-square-foot home that has a nearly direct view of the Tampa Bay Buccaneers quarterback’s under-construction manse on Indian Creek Island.

Proving their troubled marriage was already doomed, Bündchen first viewed the mansion on Aug. 16, days before Brady’s shocking 11-day break from the NFL — which was said to be a last-ditch attempt to save their relationship. She closed on the property on Oct. 6.

“Gisele was actively looking at homes in Miami Beach even before Tom took his break from the NFL, which indicates that she was already done with the marriage and moving on,” a source tells Page Six.

Brady’s in-the-works mansion has a waterfront view of Biscayne Bay, while Bündchen’s new home is in Surfside, almost directly across the narrow waterway also known as Indian Creek.

“You could literally swim from Gisele’s place to Tom’s — not that they would — but both homes will include a dock, so it would be very easy for them to co-parent their children while living so close to each other,” the source tells us.

The former couple will share joint custody of their kids following their Oct. 28 divorce.

Bündchen’s home sits on a 18,400-square-foot waterfront plot. The property listing states it has soaring 25-foot ceilings, numerous terraces and views of a wide waterway plus Indian Creek Island.

It also has a large outdoor pool, home theater, office, gym, playroom and an eat-in kitchen that opens up to a patio. The master bedroom is on the ground floor and features his-and-hers baths. It is located on a private cul-de-sac, offering Bündchen, 42, and their kids, Benjamin, 12, and Vivian, 9, more privacy. (The athlete also shares son Jack, 15, with ex Bridget Moynahan.)

Brady, 45, is believed to be keeping their property on Indian Creek Island — also known as the Billionaire Bunker, an exclusive enclave of wealthy residents including hotel magnate Jeffrey Soffer, Ivanka Trump and Jared Kushner and activist investor Carl Icahn.

The NFL player and his now-ex-wife purchased the $17 million plot of land on Billionaire Bunker in late 2020. They then tore down a 5,772-square-foot home on the lot and began building an eco-friendly mansion in its place.

The property remains under construction.

In December 2020, the legendary football player purchased a 40-foot, ultra-modern boat named Vida a Vida after Bündchen’s environmental initiative.

Meanwhile, sources say Bündchen — who this week was spotted vacationing in Costa Rica with their children — has been recently staying at a rented property in Miami while she gets her new homes ready.

It is believed she will carry out a dramatic renovation of the new Surfside mansion to put it on par with her other properties, which have always been eco-friendly.

The move comes after The Post last month confirmed Bündchen purchased a modest $1.25 million property also in the Surfside area.

She closed on the three-bedroom, three-bathroom, Art Deco-style cottage on Feb. 28 and then submitted plans to remodel the property.

It is only half a mile from her new, much larger mansion, and it is believed the cottage will be used as an office or possible staff residence.

Bündchen filed for divorce from Brady in Glades County, Fla., on Oct. 28 after 13 years of marriage and 15 years together. He did not contest the filing, and the dissolution of their marriage was finalized the same day.

The former Victoria’s Secret Angel wrote on her Instagram Story, “My priority has always been and will continue to be our children whom I love with all my heart.

“We have grown apart and while it is, of course, difficult to go through something like this, I feel blessed for the time we had together and only wish the best for Tom always.”
