The Brazilian beauty married Tom Brady in February. They have been together since he split from longtime ex-girlfriend Moynahan back in 2006.
Moynahan announced that she was pregnant with Tom's child, John Edward Thomas Moynahan, now 17 months, just weeks after the two split.
Bundchen recently gushed in Vanity Fair that she has a great relationship with the boy, even claiming she felt as if he was "100 percent" her child.
Gisele probably only meant that in the sense that she is wholly committed to her role as a stepmother to John, but the model's comments were not received favorably by Moynahan, according to a report in the New York Post.
A pal of Bridget Moynahan's said "If Gisele loved Bridget's child like he was '100 percent her own,' then she would not talk about him in the press."
"Don't you think Jack will grow up and read her comments and find them disrespectful to him and his mother? If Tom Brady 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?"
"Is she really so desperate for attention that she can't find anything more productive to talk about other than Bridget's child?"
