Monday night Zelda Williams, the only daughter of Robin Williams, tweeted a quote from the famous children's book The Little Prince, along with the words "I love you. I miss you. I'll try to keep looking up."
Robin Williams' last post online was a message to Zelda in honor of her 25th birthday, which read: "#tbt and Happy Birthday to Ms. Zelda Rae Williams! Quarter of a century old today but always my baby girl."
