Close friends and family came together under a tent outside the Travoltas' house in Ocala, Fla., to remember Jett.
According to the Ocala Star-Banner, James Gandolfini, Garth Brooks and wife Trisha Yearwood, Forest Whitaker, Lisa Marie Presley, Kirstie Alley and Cal Ripken Jr. were among the 100 or so people in attendance.
A female minister from the Church of Scientology was the only one who spoke during the hour-long service and, when the service ended, John and Kelly reportedly kissed a large photograph of Jett that stood behind the minister's podium.
A steady stream of fans and supporters left gifts and sympathy cards with the security officers at the front gate of the estate throughout the day.
We pray John, Kelly and their family find a way to heal and move forward.
