Rumors have been circulating about a possible pregnancy for the newlyweds since pictures showing the supermodel with what appeared to be a baby bump surfaced this week. Bündchen, 28, and Brady just tied the knot -- twice -- this spring. They first held a ceremony in Santa Monica, Calif. on Feb. 26, and again exchanged vows before close friends in early April at Bündchen's Costa Rica home.
The child would be the Brazilian model's first. But she has already been playing stepmom to Brady's son, 1-year-old John Edward Thomas Moynahan, who he had with his ex-girlfriend Bridget Moynahan. Bündchen touched off a row when she said she considered Moynahan's son hers, a claim Moynahan did not appreciate.
There won't be any dispute about this one, however.
"Gisele will be an excellent mother," a source tells PEOPLE. "She's always wanted kids."
“Family is everything," Bündchen told PEOPLE last month. "I think family is the base to everything. I think that is one of the things I’m most grateful for. I have a lot to be grateful for but I think that's definitely number one.”
Another friend close to the couple says, "You know Gisele and Tom are just enjoying themselves, being married and just doing their thing ... Gisele has been talking about it with friends. She says she's ready for a family."
Gisele is due early next year.
