Gisele Bündchen is still riding solo in South Beach -- the supermodel was spotted at a Miami gym by herself Monday morning ... days after she and Tom Brady reportedly decided to remain separated during Hurricane Ian.
Gisele and Brady were forced to evacuate Tampa Bay as the tropical storm arrived last week ... but not even Ian could bring the two back together amid their alleged rift, according to Page Six.
While Brady returned to Tampa for the Buccaneers' home loss to the Kansas City Chiefs on Sunday, Gisele elected to stay south and pass on watching her husband in person .
