Check out that itsy bitsy bikini!

Gisele Bundchen is seen heading to the pool in a skimpy bikini while vacationing in Rio de Janeiro with husband Tom Brady over the weekend. The pair returned to Bundchen's native Brazil to celebrate the country's largest and most popular celebration, the Rio de Janeiro Carnival held in the city.

Bundchen got to be a part of the celebration as she rode atop the float for the Vila Isabel samba school as it paraded into the Sambadrome during the first night of the two-night celebration. The extravagant Carnival sounds much like Mardi Gras in New Orleans with a plethora of parades and partying in the streets for days.

There wasn't a shortage of celebrities either. Jude Law was caught mid smooch, and Pamela Anderson was seen with a new man, enjoying the Carnival as well.

Look at the photos below of Gisele in the parade and taking in the sights with Brady!
