How Gisele Bündchen Kept Her Third Pregnancy a Secret

After a source confirmed to PEOPLE that Gisele Bündchen, 44, and boyfriend Joaquim Valente, 35, are expecting their first baby together, Bündchen's third, on Monday, Oct. 28, fans were left wondering how she kept her pregnancy hidden for months.

Bündchen frequently shares her son Benjamin Rein, 14, and daughter Vivian Lake, 11 — who she shares with ex-husband Tom Brady — on her social media, but the model gave no impressions that she was expecting her third baby.

Earlier this month, the model shared an Instagram Reel promoting an herbal supplement brand, which was meticulously shot from the chest up.
