Newlywed supermodel GISELE BUNDCHEN has sparked rumours she's expecting her first child with husband TOM BRADY - after the pair were photographed leaving an obstetrician's office.

The Victoria's Secret model and American football star Brady visited a Manhattan-based OB/GYN on Monday, three months after they exchanged vows in a Catholic ceremony in Santa Monica, California.

They celebrated their union with a larger ceremony and wedding reception in Costa Rica weeks later.

Gisele and Tom began dating after his 2006 split from actress Bridget Moynahan, with whom he shares a 17-month-old son, John Edward Thomas Moynahan.

A spokesperson for Bundchen tells the New York Post, "We have no comment on our clients' personal lives."
