Robin Williams' Daughter Zelda Pays Tribute on Late Actor's Birthday

— -- Robin Williams would have been 65 today.

The icon died almost two years ago and his family, including his beloved daughter Zelda, is still grieving the loss.

Zelda, 26, took to Instagram today to share a sweet, candid photo with her dad and brothers from when she was just a kid.

"Still not really sure what to do on days like today… I know I can’t give you a present anymore, but I guess that means I’ll just have to keep giving them in your name instead," she wrote.

She continued, "This year, I tried to help three causes you cared about in one; rescue dogs, people suffering from disabilities, and our nation’s wounded veterans, so I donated to freedomservicedogs.org. They rescue pups from shelters and train them so that they can be paired with someone in dire need of their help and companionship. Thought you'd get a kick out of furry, four legged friends helping change the world, one warrior in need at a time. Happy birthday Poppo. Shasha, Zakky, Codeman and I all love you and miss you like crazy. Xo."

The comedic legend died on Aug. 11, 2014, after taking his own life at his California home. It was later revealed he had been diagnosed with Parkinson's disease and was dealing with depression at the time of his death.
