The World’s Top-Earning Supermodel is ready to trade in her Manolos for motherhood.

Gisele Bundchen has bonded so well with boyfriend Tom Brady’s small son, John, the former Victoria’s Secret vixen wants a tiny-Tom of her very own, a Star Mag snitch says.

“Gisele bathes him,” the insider says of the catwalk maven’s relationship with lilttle John, “She snuggles him, changes diapers and does everything else a mom does for her child. She feels this connection with him.”

“She knows John has a mother, Bridget Moynahan, and it just makes her want her own child with Tom.”

The Brazilian-born beauty “has let Tom know that she’s ready and willing.”

But Tom isn’t sold on the idea of having another child.

“He likes his life the way it is…Tom loves what he has with Gisele and doesn’t want to ruin it.”
