14-year-old Brit twins Max & Harvey Mills began harmonizing together at the age of five and started singing when we were about eight. Both developed a passion for acting, appearing in commercials, on television shows, and in West End Theater productions. They have amassed millions of fans on Musical.ly and are now Britain’s biggest Musers -the name given to the users of the insanely popular social music app launched from Shanghai in 2014. "One more day to love" is the title of their début video directed by Raja Virdi. The boys are nominated at this year's Shorty Awards.
