Washington, June 25 : If sources are to be believed, `pregnant' Gisele Bundchen is due to give birth on December 14.

The supermodel's recent photograph with her hubby Tom Brady leaving a New York obstetrician''s office has been the source of speculation for the pregnancy.

To add to it, she also wore baggy clothes during a catwalk at Sao Paulo fashion week and appeared in a new advert campaign for Loewe with oversized handbags hiding her stomach.

"Gisele has always wanted to be a mom, and she is deeply in love with Tom. This is the happiest she''s ever been," Contactmusic quoted a source as telling Life and Style Weekly magazine.

While on TV show Fantastico, Gisele hinted she was ready to have a baby after revealing she loves helping to care for Tom''s 21-month-old son John from a previous relationship.

Bundchen said: "I am crazy about children. I am an adoptive mother. I''ve already had this experience for two years." (ANI)
