Gomez and Delevingne made several official public appearances together after they were pictured on the Lacma Art + Film Gala red carpet, but nothing was more notable than the BFFs appearing in Taylor Swift's iconic "Bad Blood" music video. The video stars Selena as Asrysn, someone who fights alongside Swift's character (Catastrophe), only to betray her. Delevingne plays the role of Mother Chucker, who is a part of Taylor's army of fighters.
Gomez previously opened up to Billboard about her experience shooting the video with two of her best friends in 2015, saying, "It was just fun. I don't think it even counts for work," Gomez said. "We were there until 4 in the morning, just sitting on the couch, eating In-N-Out burger, talking about boys, and then we'd go and pretend we were killing each other. Good times."
