A pro-Palestinian speech and performance by Macklemore, opening for Ed Sheeran at MetLife Stadium on Sept. 4, has triggered an ongoing celebrity fallout. Wearing a keffiyeh, Macklemore called for "Free Palestine" and performed his protest song "Hind's Hall" before the crowd, according to CBS New York.

Pink publicly criticized the set as "awful" and called on Sheeran to apologize and refund fans, according to TMZ. A petition from the Israeli-American Council is now pressing Sheeran's Loop Tour to remove Macklemore from remaining dates, while critics accuse Pink of trying to silence political speech. Neither Sheeran nor Macklemore has responded publicly to Pink's comments.
