"The world lost a real princess who only wanted to make the future happy for all," he said. "Acting was just a childhood dream come true and she had big plans for the future."
Griggs died on Nov. 5. The teen was laid to rest at a funeral in New York on Friday and her family planned a remembrance service to celebrate her life for Sunday.
Griggs made her Broadway debut in 2012 at age 6, playing Ivanka in the musical "Once" alongside actor Steve Kazee. She performed the role until 2015, the longest time an actress has played the part. She also played Polly in the Tennesee Williams play "Cat on a Hot Tin Roof" on Broadway in 2013 alongside Scarlett Johansson.
Griggs also did some onscreen acting work. She starred in commercials and provided the voice of several characters on the popular Nickelodeon children's animated series "Bubble Guppies." She also starred in the 2016 movie "Caf Society" with Steve Carell, Jesse Eisenberg and Kristen Stewart and had a couple of uncredited parts on "Saturday Night Live" in 2017.
