New details have emerged from the private Malibu ceremony honoring the life and legacy of Hayden Panettiere. 'Us' exclusively learned that the intimate celebration, held September 19, brought together around 80 of the late actress’ closest friends for an evening of music, memories, laughter and tears. Invitations to the event were extended to Panettiere’s father, Skip, who was in attendance; however, Panettiere’s mom, Lesley Vogel, was invited and unable to attend. The event was staged five weeks after the 'Heroes' alum was found dead at age 36 in a Greenville, South Carolina, residence on August 16. An official cause of death is pending. The ceremony, which was attended by several high-profile guests including Panettiere’s former 'Nashville' costar Connie Britton, Evan Ross, and Ruby Rose, saw guests sharing stories and memories as they reflected on Panettiere’s lasting impact on others. Sanoe Lake, a close friend to Panettiere, arranged the event with assistance from fellow close friends Allie Beattie, Emily Buckingham and Kasey Kitchen. The group spoke to 'Us' on Sunday about their intentions. The group told 'Us,' “We wanted to honor Hayden in the best way we knew how: with as much love as possible. It was a beautiful and intimate ceremony where friends came together to celebrate her life and honor the beautiful, magnetic light and love she infused into the world.”
