During his nearly four decades in show business, Robin Williams worked with countless people now paying heartfelt tribute to the late showman.

But none may be more moving than what his daughter Zelda posted in the hours after news of his death resonated worldwide.

The 25-year-old actress shared a quote from Antoine de Saint-Exupery's book The Little Prince Monday evening in memory of her dad.

She ended the message with her own words writing, "I love you. I miss you. I'll try to keep looking up." The post has more than 46,000 retweets so far.

The Oscar-winning actor was found dead by apparent suicide at his California home Monday.

His final message on social media, posted on July 31, was a birthday message to Zelda featuring a photo of the two of them taken more than 20 years ago.

Williams was also father to Zachary, 31, and Cody, 22.

If you are wondering why Williams and ex-wife Marsha Garces named their daughter Zelda, it is apparently because Williams bought one of the first Nintendo systems and they were addicted to the famous game The Legend of Zelda.
