Rumour is rife today that Gisele Bündchen is pregnant with her second child. Modelinia is reporting that a source who is "very close" to the Brazilian supermodel has confirmed speculation that she is, in fact, expecting a new bub with husband Tom Brady.

The whispers began flooding the internet when wardrobe assistants reportedly noticed a change in Gisele's body. While other sources claim that Gisele turned to her long-time pal, Riccardo Tisci of Givenchy, and confided in him the news.

The speculation circulating is that Gisele is two months pregnant and is therefore waiting for the first trimester to officially announce the news. If true, then it would mean a baby brother or sister to the couple's first child, two-year-old Benjamin. Tom also has a son, John, 4, from his previous relationship with Bridget Moynahan.

I wonder what the Bündchen camp will have to say about this one. Will they confirm the truth or let it blow over until Gisele herself wishes to confirm or deny the rumours. Watch this space!
