Gisele Bundchen flaunted her sexy silhouette in a black two-piece bikini while vacationing with her family in Costa Rica. The 34-year-old Brazilian model was spotted with her two lovely children, Vivian and Benjamin, enjoying their beach escapade in the Central American nation.

The Costa Rica getaway was more of a family vacation, the Daily Mail reported. Bundchen's mother Vania and other family members were there to join the beach fun. Bundchen also took her dog Lua to the best playground it could ever have. However, Bundchen's better half New England Patriots' Tom Brady was missing in action. According to reports, Bundchen has a vacation home in Costa Rica.

Bundchen carried her two children on her back as they frolicked in the beach. She carried Benjamin on her back while she snugged Vivian on her hip. Apparently, Bundchen likes to carry her children all the time, especially when they were out and spending quality time as a family. In August 2013, Bundchen was also pictured carrying her children at a park in Boston. In March 2014, she also hugged her children close in Boston after a trip in Costa Rica.

Meanwhile, Bundchen reportedly had stripped for a new retro style campaign. The model has not only gone racy but also make-up free in her latest advertisement. The pictures were taken by German fashion photographer Juergen Teller for French fashion designer Sonia Rykiel.

Bundchen shared a picture on Instagram. "New @soniarykiel campaign shot by #JuergenTeller and styled by @kegrand," she captioned the photo.

Another photo showed Bundchen ditching her underwear and wearing only a thin fabric to cover her intimate area.

The inspiration for the setup came from Rykiel's old pictures dated way back in the 1970s. Katie Grand, who art-directed the campaign, saw black and white pictures of Rykiels which she thought were "elegant" and it jogged her memory with the works of the German fashion photographer Teller.

"Once Juergen had agreed to work with us, we wanted to work with a woman with Madame Rykiel's joie de vivre (joy of living), and the obvious choice was Gisele," Grand said in a statement.
