Rumors of Gisele Bundchen's pregnancy have been confirmed after the supermodel revealed her burgeoning baby bump in a bikini this week.

The world-famous model was on the beach in Costa Rica in a grey triangle swim suit when photographers captured her new figure.

Bundchen, who has been married to Tom Brady, will welcome her second child with the NFL star. They couple share son Benjamin, 3, and Brady's son John from a previous relationship, 4.

In a past interview, Bunchen opened up about motherhood brightening her life.

"My son is so cute," she exclaimed, according to the Daily Mail. "I love hearing the little giggles. When everything is going crazy sometimes you are overwhelmed and it's so much, but when your kid smiles at you, you're like, 'Oh my God, it's all worth it.'"

Just last week, the Victoria's Secret model celebrated her 32nd birthday amidst longstanding rumors of a pregnancy. She has yet to comment on her growing family though.

It is believed that Bundchen was pregnant during the 2012 Met Gala in May, and if so, the baby would be expected this winter. It is sad that the Brazilian beauty is waiting until late into her pregnancy to announce the news.

Despite her desire for a family, Bundchen is one of the highest-paid models in the world. She entered a modeling course at the age of 13, and shortly after, the Elite Modeling Agency noticed her. In 1996 she received her first break during New York City's Fashion Week, which catapulted her into celebrity.

Deemed "The Most Beautiful Girl in the World" by Rolling Stone magazine, Bundchen also inspired articles such as "… And God Created Gisele" by Vanity Fair magazine.

Internationally recognized, she has appeared on ads for brands such as Armani, Dolce & Gabbana, Ralph Lauren, and Versace, among countless others.

Moreover, this year Bundchen became the face of the luxury jewelry brand David Yurman. She also stays busy with her clothing collection, C&A, and covered the Brazilian edition of Vogue this month.
