But in the week leading up to the festivities in Central America, a soap opera involving all three adults was shaping up, kicking off with Bündchen's expansive remarks to Vanity Fair, in which she said she considered young John Edward her very own child.
"It's not like because somebody else delivered him, that's not my child," said the supermodel, 28. "I love him the same way as if he were mine. I already feel like he's my son, from the first day."
That apparently didn't sit well with those in Moynahan's inner circle. A source close to the 37-year-old model-actress tells PEOPLE, "Bridget has her own life, she doesn't need to be involved in the drama of all this, and she finds it disrespectful that her son is being paraded around in front of the paparazzi when she’s specifically made it a point of keeping him away from that."
The source went on to say pointedly, "I can count on two hands, in two years, the number of times Bridget has been photographed with that baby. I can count on two hands the number of times in the past month that Gisele has been photographed with that baby."
In an even more personal attack, the source said, "If Tom is such a great father as everyone likes to say, then you would think that he'd respect the privacy of his young child and would ask his wife not to use his son as a publicity prop and a subject of public discussion."
Moynahan on MotherhoodFor her part, Moynahan's most direct comments on the situation appeared in Harper's Bazaar. She told the magazine, "When you're suddenly pregnant and no one is standing by your side, even if you're in your 30s, it's a hard conversation. I'm a traditional girl, and I believe in marriage, and I just always thought that's the way I'd be doing this."
Moynahan, who was with New England Patriots quarterback Brady, 31, for three years before they broke up and she subsequently announced her pregnancy, added, "For a moment, it was hard for me to accept that this was the way I was going to have a family."
