Bündchen is already mom to daughter Vivian Lake, 11, and Benjamin Rein, 14, whom she shares with ex-husband Tom Brady.

After announcing her baby news, a source exclusively told PEOPLE that Bündchen is “excited” about her third pregnancy.

The source said that the supermodel feels good about the pregnancy. Bündchen has not shared the baby’s sex because she is not planning to find out herself until the baby is born, the source told PEOPLE, adding that Bündchen is several months along and plans to welcome her baby at home.

“Gisele’s very happy in Miami,” the source said. “She enjoys her life there. Everyone’s thriving.”

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

“They started out as friends, but have been seriously dating for over a year,” the source continued. “She’s excited about the baby and feels good. She’s several months along and planning 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 began dating in June 2023.

“They have been dating since June. They're taking it slow,” the source said at the time. “They started out as great friends first. She's very private about this and wanted to keep it quiet while they got to know each other.”
