Robin Williams' daughter Zelda shares touching tribute to her dad

Robin Williams' daughter took to Twitter to share an emotional tribute to her father in the wake of his death on Monday.

Zelda Williams, 25, shared a quote from Antoine De Saint-Exupery's book "The Little Prince" in memory of her dad.

"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 are laughing, when you look at the sky at night...You -- only you -- will have stars that can laugh," it read.

The actress added, "I love you. I miss you. I'll try to keep looking up. Z."

Williams died Monday of an apparent suicide, at the age of 63.

His final Instagram update, posted on July 31, was to wish Zelda a happy birthday and included an old photo of the two of them.

Happy Birthday to Ms. Zelda Rae Williams!" he wrote. "Quarter of a century old today but always my baby girl. Happy Birthday @zeldawilliams Love you!"

In 2011, the pair appeared in a commercial together for Nintendo's Zelda (Williams' daughter is named for the princess in the video game series). Watch it below:
