Brazilian supermodel Gisele Bundchen debuted her baby bump while on vacation in Costa Rica.

The 32-year-old supermodel and actress, rumored to have been pregnant in June, donned a tiny gray bikini and a floppy hat while on the beach with her son Benjamin on July 24, displaying an obvious baby bump (Photos in Mail Online).

Bundchen, who is said to be the highest-paid model in the world with estimated annual earnings of $45 million, and Brady, the 34-year-old quarterback of the New England Patriots football team, married in Los Angeles in 2009. They are already parents to son Benjamin, 2.

The model has yet to comment on the reports.

In June 2012, there were reports that the Brazilian supermodel was expecting her second child.

Us Weekly magazine on Wednesday, June 6, quoted a source close to Bundchen as saying the supermodel is "three months along" and that she and Brady are "really happy." Bundchen and Brady did not comment at the time.

Brady also has a 4-year-old son, Jack, with ex-girlfriend and actress Bridget Moynahan, who plays Erin on the CBS show "Blue Bloods" and has starred in movies such as "Coyote Ugly."

Bundchen gave birth to Benjamin in a bathtub in December of 2009.
