Robin Williams' daughter tweets moving memorial to dad

Zelda Rae Williams, the daughter of Robin Williams and Filipina-American philanthropist Marsha Garces, posted a simple, powerful memorial to her father on Twitter after his death on Monday:

It's an excerpt from French poet Antoine de Saint-Exupéry's The Little Prince. It reads:

"You — you alone will have the stars as no one else has them…In one of the stars I shall be living. In one of them I shall be laughing. And so it will be as if all the stars were laughing, when you look at the sky at night…You — only you — will have stars that can laugh."

Beneath that, Zelda wrote:

"I love you. I miss you. I'll try to keep looking up."

Zelda Williams, 25, is an actress who co-starred with her dad in the 2004 film House of D.
