Gisele Bündchen's sweet birthday message for her children

Gisele Bündchen is one proud mamma! In the space of three days the Brazilian supermodel shared photos of her son and daughter, delighting fans with the sweet pictures.

Gisele chose to mark her children's birthdays on Instagram, showing her love and affection for Benjamin, six, and three-year-old Vivian.

"Happy birthday my sweet Benny! I love you so much #love #grateful," Gisele wrote alongside a photo of the mother-son duo. She followed it up with the same message in her native Portuguese.

The picture showed the little boy squeezing his mum tightly in a hug, while someone, perhaps Gisele's husband Tom Brady, took the photo from behind.

It's clear that the former Victoria's Secret model wants to keep her children out of the spotlight and give them a fairly private upbringing. Three days ago Gisele shared a photo of her daughter Vivian, again from behind.

"Happy birthday my little sunshine! I love you so much! #love #grateful," she wrote.

The Brazilian model is also the proud mum to little Vivian

Vivian, who looked sweet in a multi-coloured swimsuit, was pictured against a tropical backdrop of a bright blue sky, sandy beach and palm trees, but the youngster seemed unaware of the scenery and more focused on grabbing a birthday balloon.

In April of this year Gisele retired from the runway, with her final walk, naturally, taking place in her native Brazil.

The statuesque beauty opened and closed the show for Brazilian brand Colcci as part of Sao Paulo Fashion Week – the same place where she made her runway debut 20 years ago.

Her parents and husband Tom proudly looked on while a teary-eyed Gisele gave a wave on her final walk.

Gisele and the American football quarterback married in 2009 in an intimate ceremony in Santa Monica. The pair, who had been set up on a blind date by a mutual friend, started dating in 2006.
