Tom Brady and Gisele Bündchen exchanged vows in a short sunset ceremony at her home in Costa Rica early Saturday evening, PEOPLE has learned.

The bride, in a long designer dress and a veil that trailed 10 feet, and holding a bouquet of white orchids, looked so gorgeous, a source tells PEOPLE. She looked beautiful.

Security guards blocked off key access points to Bündchen’s house in Santa Teresa, where 25 or so guests gathered under a tent set up on the home s balcony.

After the ceremony, Brady, 31, in a gray suit and vest with white pants, held his 1 ½-year-old son John on the balcony and spoke with guests like Robert Kraft, owner of the New England Patriots. Bündchen, 28, also hugged guests while friends and relatives snapped photos.

They all seemed very happy, like they were having a great time, says one onlooker.

That afternoon, Bündchen got dressed at the nearby Hotel Flor Blanca while workers readied her home.

Around 4:30 p.m. Bündchen and other guests raced back to her home just in time for the sunset nuptials.

His-and-Her Parties

Earlier that day, Brady hosted a bachelor s brunch for the men in his entourage at the luxurious Milarepa hotel, where guests dined from a menu designed especially by the American chef.

Meanwhile Bündchen entertained female guests and went over last-minute wedding details at her home.

The separate his-and-her gatherings was the final lead up to three days of pre-wedding celebrations before the couple’s second set of nuptials. (They officially wed in an intimate ceremony in Santa Monica, Calif., Feb. 26.)
