This isn’t widely known, but Carrie Fisher and musician Sean Ono Lennon were actually good friends.
Sean wrote on Instagram after Carrie's passing: "I can honestly say that Carrie was one of the best and closest friends I've ever had in my life. She was the smartest, funniest, kindest, and most generous person I have ever known. My heart is completely and permanently broken. This is the kind of loss that you never recover from. I know because I still miss my dad every single day."
