Tom Brady was reportedly “stunned” to learn about Gisele Bündchen’s pregnancy with boyfriend Joaquim Valente. After news of the supermodel expecting her third child broke on Monday, October 28, a source exclusively told Page Six that the seven-time Super Bowl winner, despite knowing things were serious between Bündchen and Joaquim, was slightly spooked. “It just wasn’t something that was on his radar. So when Gisele broke the news to him, he was stunned, to say the least,” the insider divulged. The tipster, however, added that “after the initial shock wore off,” Brady, who shares son Benjamin Rein, 14, and daughter Vivian Lake, 11, with Bündchen, has “grown used to the idea and is happy” for her. “At the end of the day, Tom’s sole focus is on his children and his career. What Gisele decides to do with her own life is really none of his business.” ALSO READ: ‘Can I Sail Through…’: Gisele Bündchen’s Ex-Husband Tom Brady Shares Cryptic Instagram Post Amid News Of Supermodel’s Pregnancy Bündchen and Valente, her and her children’s Jiu-Jitsu instructor, were …
