Yesterday, Feb. 20, marked what would have been the 50th birthday of Nirvana icon Kurt Cobain. The lasting impact of his music speaks for the legacy he left, but on this special day Kurt's daughter found time to remark how grateful she was for something other than the the music: life.

Posting a handwritten note from the heart on her Instagram page (seen below), Frances Bean Cobain wrote, "Today would have been your 50th birthday. You are loved and you are missed. Thank you for giving me the GIFT of life. Forever your daughter, Frances Bean Cobain."

Frances also corresponded with her grandmother yesterday, delighting in being raised by someone so "strong and compassionate." Posting a screenshot of the text conversation on Instagram (seen below), 'Grams' responded, "Ohhhh, what beautiful words, from his beloved daughter. You were such a caring, loving little girl and have turned into such a beautiful young woman, he would be so 'smugly' proud of you, saying, 'Yeah that's MY daughter.' I love you with all my heart. Thank God you were here for me to love and care for."

Earlier this year, we reported that Frances was still engaged in a legal battle with her estranged husband, Isaiah Silva, over one of Kurt's most coveted guitars. The 1959 Martin D-18E acoustic was used for Nirvana's MTV Unplugged performance and Silva is claiming it was given to him by Frances, though she disputes that she never would have gifted away such an item.
