Not everyone who is on top of the fast-moving pop music scene has heard of Charlotte Aitchison, even by her stage name Charli XCX, but lots of people have heard her or her songs. At 22, the English singer is also a seasoned songwriter, having written and featured on international smash hits “I Love It” with Swedish pop duo Icona Pop, and “Fancy” with female rapper Iggy Azalea. “I Love It” hit No. 1 in Britain, and went two times platinum in the United States, while “Fancy” held No. 1 on the U.S.
