Lorde is encouraging her Missouri fans to push back against the Westboro Baptist Church.
The controversial organization is planning to picket the 17-year-old singer's Kansas City concert on Friday, amid reports that their founder Fred Phelps is on his death bed.
A statement from Westboro calls Lorde "a young lassie that doesn't have enough sense to put in a thimble" and who the world has elevated "to the status of an idol."
Billboard says Lorde tweeted and deleted a message to fans, urging them to fight back against organization's hate.
She apparently asked her followers to "wear rainbow clothing" to the concert and "try to kiss church members who are the same sex as you."
