Actor "Moesha" and "Everybody Hates Chris," has died at the age of 54.

The cause is not yet known, but his manager Cindy Ambers told the Los Angeles Times that he suffered a heart attack two years ago.

Harris grew up in Long Beach, California and was a childhood friend of Snoop Dogg. He began his career as a performer on HBO's "Def Comedy Jam" and made his acting debut in "Poetic Justice" opposite Janet Jackson and Tupac Shakur. He also had roles in television shows including Moesha and memorably as a charming neighbor on "Everybody Hates Chris." Harris most recently appeared in "The People v O.J. Simpson."

Harris is survived by his mother, ex-wife, and two daughters. Friends and fellow celebs reacted to his death on social media:
