Fisher died December 27, 2016, four days after going into cardiac arest onboard a flight from London to Los Angeles. "I'm beyond proud. @RecordingAcademy", Billie captioned a throwback photo of herself on a red carpet with her mother and a pic of Carrie's memoir.
The award was announced during the preshow ceremony before Sunday's televised awards show. Fisher's daughter, Billie Lourd, paid tribute to her mother following the announcement.
Fisher took on a competitive group of nominees, winning over Bernie Sanders and Mark Ruffalo who were nominated for the audiobook version of Sanders' Our Revolution: A Future to Believe In. This memoir was based on the handwritten diaries that young Fisher kept during the filming of Star Wars, which began when she was 19 years old.
The actor has been nominated for different awards after her death, including at the 2017 Emmy Awards when she was in contention for Outstanding Guest Actress in a Comedy Series fro her role on the Amazon Original Series Catastrophe. She also spoke to a then-pregnant Savannah Guthrie (whom she, in very Carrie fashion, told "congratulations on the sex") about having an affair during her first-ever film.
Among them was the late Carrie Fisher, who ended up the posthumous victor of her first Grammy. She was previously given the Outer Critics Circle Award for Outstanding Solo Performance in 2010 for her 2008 autobiographical humor book Wishful Drinking.
