She's like wine that gets better with time.

On Sunday, Gisele Bundchen celebrated her 34th birthday with her twin sister Patricia at an undisclosed tropical location.

The supermodel, who sported a bikini, and her equally beautiful sister blew out candles on a cake that was surrounded by yellow flowers. Palm trees and the blue ocean served as their background for the shot.

Bundchen shared the twins' special moment on her Instagram, with the caption, "Thank you for the love and birthday wishes. I feel so blessed. #grateful."

The Brazilian born model had been in the undisclosed tropical spot since Thursday. She kicked off her vacation with a handstand on the beach.

"Finally on vacation," Bundchen captioned the photo, which showed her doing the cartwheel in a pair of black bikini.

Bundchen, who is mom to 4-year-old Benjamin and 2-year-old Vivian with husband NFL player Tom Brady, recently landed on Forbes magazine's 2014 Celebrity 100 List.

The magazine, which tracks Bundchen's earnings since 2001, said the supermodel earned $47 million - or $128,000 a day - from her modeling contracts with Chanel, H&M, Carolina Herrera, Isabel Marant and more.

Aside from her modeling gigs, Bundchen was recently seen by her fellow Brazilians during the 2014 World Cup, when she was tasked to unveil the trophy before the final match between Argentina and Germany.

The model, however, refused to confirm her net worth.

"It's sad, because the people who write these things don't have my bank account details," Bundchen said earlier this year, according to Mail Online. "I do OK. I earn plenty, but not as much as they say. I've already been audited by the IRS because of this list and, truthfully, whether I'm on this list or not doesn't interest me."
