Just 10 days after attending his aunt's Brazilian wedding, Gisele Bündchen and Tom Brady's son Benjamin celebrated his 4-month birthday with a family day out in Paris. Under warm skies, the trio, joined by Bündchen's mother and sister, took off from their hotel for a private 90-minute lunchtime cruise along the Seine aboard a 72 ft. charter yacht. "Gisele carried Benjamin on board wrapped in a white blanket," one onlooker told PEOPLE, adding, "The baby's very pretty. He's very active – looking everywhere."
And he had a lot to see.
From Bastille the yacht sailed downriver beside Notre Dame, the Louvre, Concorde and moored beneath the Eiffel Tower. "Tom and Gisele and Benjamin were posing for family pictures, kissing the baby and each other," the onlooker says. With lunch onboard prepared by chef Jean Pierre Vigato in a salon, the couple took turns holding Benjamin while they ate on the deck.
After sailing back, Gisele and Tom took their son to one of Paris's legendary sweet shops, Angelina's, where they enjoyed ice cream before Bündchen and Benjamin hit the shops. Gisele stopped into Maria-Luisa for Men on Rue Mont Thabor. "Gisele comes in from time to time," says a shop employee. "This time it was a surprise. The baby was sleeping very peacefully in Gisele's mother's arms."
Next, it was time to get something for Benjamin, so the group stopped into Tartin et Chocolat on the Faubourg Saint-Honoré.
"He's a beautiful baby," says the shop's director, Madame Edith. "With a mother and a father like his, how could he not be?"
