There has been speculation that she's retiring from the catwalk.

But Gisele Bundchen hasn't given up on modeling completely and delighted her Instagram followers when she stripped down to her undies to promote her lingerie line Gisele Bündchen Intimates.

The 34-year-old Brazilian beauty can be seen in a purple lacy bra and panties set as she gazes at the camera showing off her incredible figure.

Her sun-kissed locks are tousled in beachy waves and she looks flawless with just a touch of eyeliner and lipstick.

She captioned the shot: 'Behind the scenes of my new @giselebundchenintimates butterfly collection.'

The leggy model is currently enjoying a beach getaway with husband Tom Brady and their children Benjamin, five and Vivian, two in Costa Rica.

No doubt their holiday destination of Costa Rica is a special place for the couple as they were married there in a Catholic ceremony back in February 2009 and also have a holiday home in the Central American country.

Although Gisele has not yet commented on the reports about her alleged retirement, many industry insiders are already speculating that her decision to take a step back from the catwalk has been motivated by her desire to spend more time at home with her husband and two children.

According to some sources, it has always been Gisele's dream to finish her catwalk career in her native Brazil, which is where her fashion career first began all those years ago.

Her most notable recent runway appearance was during Chanel's 'feminist protest' catwalk show in Paris in September last year, when she walked alongside the likes of Kendall Jenner, Cara Delevingne and Gigi Hadid.

The leggy beauty made her debut on the runway for the American underwear label in 1999, and went on to make more than eight catwalk appearances as a Victoria's Secret Angel.
