Travie McCoy may sing about wanting “to be a billionaire so frickin’ bad”… But Gisele Bündchen is thisclose to actually becoming one.

The 31-year-old Brazilian bombshell is well on her way to becoming the world’s first billionaire supermodel, partly due to her new lingerie line, according to Forbes.

Bündchen earned a reported $45 million between 2010 and 2011, according to reports. And that number doesn’t include the launch of her Gisele Bündchen Brazilian Intimates collection last May. The line has been a tremendous success in Latin America, Portugal, Japan, and Israel—boosting one Brazilian retailer’s turnover by 40 percent. And, the line will soon be available worldwide.

In addition, Bündchen inked new endorsement deals with Versace and Dior, as well as appears in Givenchy‘s spring 2012 ad campaign.

Bündchen’s earnings helped her and husband Tom Brady clinch the title of Highest Paid Celebrity Couple in 2011, edging out Jay-Z and Beyonce.

Forbes says its possible the supermodel could end her remarkable career with a 10-figure bank account.
