Selena Gomez likes to keep it real. During a very candid interview with YouTube star Lilly Singh, the ?Good For You? singer played the ?Newly Friend Game,? where the two get to know each other through a series of personal questions. Towards the end of the video, Gomez admits that her long, beautiful hair is ?very fake?. Viewers also learn that the 23-year-old?s favorite Taylor Swift song is ?Wildest Dreams? and ?Bad Blood?--of course. Selena's favorite song from her own Revival album is ?Kill Em With Kindness?.
