Meanwhile, the Lily's follow-up to 2009's It's Not Me, It's You is officially in motion.
In June, the singer posted on Twitter, ""You will be pleased to know that I am currently in the fucking studio with @GregKurstin," a producer who was integral to her It's Not Me, It's You work.
"It's great to work at my own pace, with no commitments other than to make music," said Cooper. "I'm excited to be heading back into the studio," she said in a statement (via Rolling Stone.)
