Don't be fooled -- while Joan Rivers' unfiltered brand of comedy didn't always show it, the legendary entertainer had a heart of gold.
Rivers died Thursday in New York City, daughter, Melissa, confirmed on the comedian's website. The 81-year-old had been rushed to Mount Sinai Hospital on Aug. 28 after she stopped breathing during throat surgery at a nearby clinic. She spent the past week in and out of intensive care treatment.
While Rivers will be remembered as a comedic star, her selflessness left an immeasurable impact on the causes near and dear to her heart.
Rivers supported nonprofit God's Love We Deliver for decades, delivering food to HIV/AIDS patients and their families in New York City. In an interview with E News posted on the organization's YouTube channel last year, Rivers talked about her experiences trying to help friends in the early days of the epidemic.
"So many of my friends in those days were getting 'gay pneumonia,' and then when it became known as AIDS, people didn't want to touch these people," Rivers told E News. "They couldn't get help. There was one hairdresser that was a very good friend of mine, and we said, 'let's start bringing him food,' and it started to grow."
God's Love We Deliver provides about 4,500 meals daily to its community. Roughly 90 percent of those served live below the poverty line.

Rivers was also an avid supporter of the American Foundation for Suicide Prevention, where she served as an honorary director. The issue directly affected Rivers' life, as her husband, Edgar Rosenberg, took his own life in 1987.

Rivers used her star power to raise awareness for those living with visual impairments. A longtime supporter of Guide Dogs for the Blind, Rivers was slated to be a guest of honor at the organization's Canine Heroes Auction on Sept. 20. The California school, which connects qualified guide dogs with individuals who are blind or have low vision, provided a statement on its website offering condolences for Rivers' family.

Several celebrities quickly took to social media and released statements regarding the comedian's death. Actor and fellow comedian Louis C.K. shared his thoughts on the legendary entertainer.
"She loved living and working," Louis C.K. said of Rivers, according to the Associated Press. "She was kind. She was real. She was brave. She was funny and you just wanted to be around her. I looked up to her. I learned from her. I loved her. I liked her. And I already miss her very much."
