The mother-of-two-to-be carried a nude handbag and a navy blue baseball cap and wore her hair in a braid down her back.

Bündchen is expecting her third baby, her first with boyfriend Joaquim Valente. She is already mother to daughters Vivian Lake, 11, and Benjamin Reign, 14, whom she shares with her ex-husband Tom Brady.

After announcing that she was pregnant again, a source exclusively told PEOPLE that Bündchen was “excited” about her third pregnancy.

The source said the supermodel is feeling good about the pregnancy. Bündchen hasn't revealed the baby's gender because she doesn't plan on finding out on her own until the baby is born, the source told PEOPLE, adding that Bündchen is already several months along and plans to welcome her baby home .

“Gisele is very happy in Miami,” the source said. “She enjoys her life there. Everyone is fine.”

Bündchen feels “very lucky” to have met Valente, a jiu-jitsu instructor, the source added.

“They started out as friends but have been dating seriously for over a year,” the source continued. “She is happy about the baby and feels good. She’s been here for a few months and is planning on having a home birth.”

Bündchen and Valente were first seen together in November 2022. They denied having a romantic relationship for months, but a source told PEOPLE in February 2024 that they started dating in June 2023.

“They have been together since June. They’re taking it slow,” the source said at the time. “In the beginning they were good friends. She is very private about it and wanted to keep it a secret while they were getting to know each other.”
