Gisele Bundchen, aka the world's highest earning supermodel, is about to become a whole lot richer, according to Forbes.

Not only does the mag predict Gisele will become the world's first billionaire supermodel, but she'll also become the first self-made billionaire from her native Brazil. Way to go, Gisele!

The 30-year-old Victoria's Secret Angel has been on Forbes' Celebrity 100 list for 10 years, and the publication predicts: "Bundchen could add as much as $19 million per year to her estimated $45 million annual income."

In addition to being the biggest supermodel in the world, Bundchen also has a lingerie line, a skin-care line, and even a sandal line.
