Joan Rivers' daughter Melissa was on hand to accept her mother's first Grammy Award at the prizegiving on Sunday (08Feb15), calling the posthumous win "bittersweet".

The late comedienne landed the Best Spoken Word Album trophy for her memoir Diary of a Mad Diva, beating out the likes of James Franco, singer Gloria Gaynor and former U.S. President Jimmy Carter.

Melissa, along with her 14-year-old son Cooper, attended the Los Angeles ceremony to accept the prize, and she tells E! News, "It's a difficult moment. It's a little bittersweet. She was nominated once for her comedy album - was never nominated once for any other books. And it's like, now she goes and wins? But it's wonderful how loved she was and how she's getting so much attention now, and people really understanding what she was about."

Rivers was previously nominated for Best Comedy Album in 1984 for What Becomes a Semi-Legend Most?

The veteran comedienne passed away aged 81 in September (14), a week after she suffered a cardiac arrest during a routine throat procedure.
