Charli penned the song with Patrik Berger (Robyn, Lana del Rey). The Swede also co-wrote and produced "I Love It
" as well as four other Sucker
cuts. Charli told Spin
magazine the pair like to write fast and spontaneously. "We just go to his place and we'll write till like 5 a.m. and get up and 10 and do it again," said the English songstress. "We don't think - it's like the first thing that comes out of my mouth is the cut on the record. I always think that if it's there in the first half hour it's probably really good, and if it's not you should move on."
