Three years ago, Williams passed away after committing suicide by asphyxia. He was 63 years old.

After news of his death broke, Gellar, 40, released a statement to People, calling Williams the father she "always dreamed of having."

"My life is a better place because I knew Robin Williams," the Buffy the Vampire Slayer star said. "There are not enough adjectives to describe the light he was, to anyone that ever had the pleasure to meet him. I will miss him everyday, but I know the memory of him will live on. And to his family, I thank them for letting us know him and seeing the joy they brought him. Us crazy ones love you."
