Break out the blue balloons: It’s a boy!

Kelly Preston and John Travolta — who announced they were expecting this past May — are having a son, Preston’s rep confirms to PEOPLE.

On Aug. 8, the couple celebrated their happy news with some 40 close friends at a shower held at their Los Angeles-area home.

The intimate outdoor gathering, which featured a bird’s nest theme by Lady Liberty Catering & Event Planning and a three-layer cake from baker Dorie Kinney, “was a wonderful day,” says shower co-host Keisha Whitaker.

The joyful occasion marked continued healing for Preston, 47, and Travolta, 56, whose son Jett suffered a fatal seizure at age 16 in January 2009.

Says a family friend: “This baby is such a healing baby.” He will join big sister Ella Bleu, 10.
