Tom Brady and Gisele Bundchen may be expecting their fourth child, but if they are, they aren't quite ready to announce the news publicly. Following weeks of rumors claiming the model may be pregnant with her third child, the fourth for Brady (who also has an older son with ex-girlfriend Bridget Moynahan), Bundchen has been keeping a low-profile on social media.

While Bundchen regularly shares photos of her family, including her and Brady's children (son Benjamin and daughter Vivian), she hasn't posted any new updates in the last week. Instead, she's been spending some time in Los Angeles, where she and her sister were recently seen shopping.

On January 12, Tom Brady's wife was seen shopping at Whole Foods with her younger sister, Gabriela Bundchen, In photos, Bundchen was seen wearing a pair of light blue jeans and a gray top, which she paired with a long scarf. Meanwhile, her hair was left in long, wavy curls. She was also sporting brown boots and a black Chanel purse. As for a potential baby bump, Bundchen did not appear to be carrying any extra weight. Instead, she looked to be her typically thin self.

Gisele Bundchen appeared to be sporting a baby bump last month

Rumors regarding Bundchen's alleged third pregnancy seemed to be confirmed at the end of last month when the model and wife of Brady was seen participating in a photoshoot.

In photos shared by TMZ at the time, the model appeared to have a clear baby bump as she was featured in a tight blue dress and a jean jacket. However, as the outlet pointed out, the roundness of Bundchen's midsection may also have been the result of a big lunch.

Tom Brady began dating Gisele Bundchen in December 2006, months before his oldest son, John Edward Thomas Moynahan, was born.

Then, in 2009, the couple tied the knot in Santa Monica, California.
