Monday marked what would have been Kurt Cobain's 50th birthday, and his daughter, Frances Bean, paid tribute to him in a beautiful way. The 24-year-old, who was not even two when her father committed suicide in April 1994, posted a letter she wrote to her dad on Instagram. "Today would have been your 50th birthday," she wrote. "You are loved and you are missed. Thank you for giving me the gift of life. Forever your daughter, Frances Bean Cobain." Beautiful.
