If Antony/Flea/Twiggy died..it would hurt. whenever I was sad when I was young I play their music and I'd feel better. Cheesy or not it helped me growing up.
if manson/Dero/Gwen died...I'd cry for like 20 minutes and get over it.
I would honestly never be the same again. Some of yall may think this is stupid, but Rihanna's music and attitude has helped me so much throughout my life. Even kept me from committing suicide a few years ago.
I'd cry for a long time and then I'd listen to all her albums and unreleased material, watch all her music videos and tours and performances and interviews for about one entire month mourning the loss of one of the most amazing people ever. Then I'd probably go out and buy even more albums, even if I own them, and a bunch of merchandise. Then pray for her to go to heaven.
I'd be sad and concerned for her son first. Then I'd be really overdramatic and cry it out, then just force myself to accept it because there's nothing else you can do
