A very excited source revealed that the model is officially expecting a child at the beginning of next year, reports People.
Rumours began to brew when photos of the beauty in Brazil showed her sporting a baby bump.
Bündchen and New England Patriots star, Tom Brady, were wed last spring.
The source stated, "Gisele will be an excellent mother. She’s always wanted kids."
Reps for the star have refused to comment on the news.
This will Bündchen’s first child, though Brady already has a son, John, with his former partner, Bridgen Moynahan.
