Gisele Bündchen's Boston Bump

Mom-to-be Gisele Bündchen tried to keep her baby bump under cover in Boston today with the help of a strategically placed sweater - and her dog Vida! - but she did reveal a quick glimpse of her growing belly.

The supermodel and her husband Tom Brady have yet to confirm the baby news, though a source from Gisele's recent London Fog photo shoot did it for them:

"Nobody is sexier or more beautiful than Gisele Bündchen in nothing but a London Fog trench coat, even with her visible baby bump," said company exec Dari Marder.

According to People magazine, the baby is due early next year.
