With the plans for her baby shower under way, Kelly Preston had two requests: an intimate outdoor setting and her favorite orange pumpkin-spice cake on the menu. The beaming mom-to-be, 47-whose rep confirms to PEOPLE that the baby is a boy-got both wishes on Aug. 8, when several of her closest girlfriends threw a shower at the Los Angeles-area home the actress shares with husband John Travolta, 56, and their daughter Ella Bleu, 10. Says cohost Keisha Whitaker: "We just wanted to make sure it was a wonderful day."

The joyful occasion-followed by another shower over high tea at the Peninsula Beverly Hills hotel a week later-marked continued healing for Preston and Travolta, whose 16-year-old son Jett suffered a fatal seizure in 2009. "After tragedy, to have such peace and happiness is wonderful," says a family friend. "This baby is such a healing baby." Preston and some 40 guests at the shower feasted on a buffet that included truffled macaroni and cheese and baby pigs in a blanket from L.A. caterer Lady Liberty. Baker Dorie Kinney crafted a three-layer cake to complement the decor's "nesting" theme. At the party's end, guests received custom-designed chocolate birds in gilt-edged nests from chocolatier Lee Gelfond. "We all had an amazing time," says Whitaker. "Kelly was overjoyed with the celebration, as well as all the love in the air."
