Gisele Bündchen Shares First Bump Photo Since Expecting Baby No. 3

This will be her first child with boyfriend Joaquim Valente.

Gisele Bündchen has been radio silent since news broke about her third pregnancy—and the first one with her boyfriend Joaquim Valente. However, yesterday, the supermodel shared a sweet message on Instagram, and her growing baby bump made its official social media debut.

In the post, Bündchen reflected on her time at the Lotus House Gala, which raises money for the largest women's shelter in America. In addition to her lengthy message about the organization's mission, fans were treated to a snapshot of Bündchen in a long, silky black gown with a high neck. The dress swathed her bump as she posed alongside other attendees.

"It was an honor to attend the Lotus House Gala celebrating their 20th anniversary as the largest shelter for women and children in America. I feel truly blessed to support the visionary Constance Collins and her incredible team, whose unwavering commitment has transformed countless lives," Bünchen captioned the image. "With their latest achievement—uniting over 300 women’s shelters nationwide through the National Women’s Shelter Network—they’re taking a bold step toward eradicating homelessness. Learn more through the link in my bio and find out how you can help. 🙏 Together, we are stronger!"

She also shared the same message in Portuguese.

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

After sharing her baby news, a source told People that Bündchen is “excited” about her third pregnancy.

Bündchen has not yet shared the baby's sex, because she is not planning to find out herself until the baby is born, the insider added, noting that Bündchen is several months along and has plans to welcome her baby at home.

"Gisele's very happy in Miami,” the source added. "She enjoys her life there. Everyone's thriving."

Speaking about Bündchen's relationship with Valente, the friend noted that the model and jiu-jitsu instructor have been seeing each other for over a year.

"They started out as friends, but have been seriously dating for over a year," the source finished. "She's excited about the baby and feels good. She’s several months along and planning a home birth."
