According to a report in People magazine, the couple will welcome an addition to their family early next year.
While the gossip mill has been buzzing for weeks about Bundchen’s growing baby bump, reps for the couple have refused to comment on the matter.
But sources told the magazine that the expectant mother is “ecstatic” at the news and that she will make “an excellent mother.”
“She’s always wanted kids,” the source said of the 28-year-old stunner.
Bundchen expressed her appreciation for family earlier this year, saying it is “the base to everything” in her life.
“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 number one.”
Brady has a son with ex-girlfriend Bridget Moynahan, who Bundchen says she loves as much as she would her own child.
