Robin Williams remembered on his 64th birthday

Robin Williams would have been celebrating his 64th birthday on July 21.

The actor, who killed himself in August 2014, was known for his roles in Mrs. Doubtfire, Good Will Hunting, Jumanji, Aladdin and more.

Williams received five Grammys, four Golden Globes, two Screen Actor Guild Awards, two Emmys, and an Oscar during his acting career.

Cee Lo Green released a song on Friday titled "Robin Williams," to honor the late actor. It is the first track off of the former The Voice judge's new album, "Heart Blanche" due November 13.

Lyrics of the song include, "We don't know what the next man's going through/ Wish I could say it in a plainer way/ We don't know life reminds me of Robin Williams/ We've got to laugh the pain away,"

" 'Robin Williams' is a homage to our humanity," Green said in a statement reported by Entertainment Weekly, "centered [on] the strength it takes to smile in the face of adversity."

The song also mentions other troubled stars who died young like Philip Seymour Hoffman, John Belushi and Chris Farley.
