Harry Styles is taking no time to kick his solo career into full gear, as the singer just announced the dates for his first-ever world tour that he'll be doing on his own. The trek begins on September 19 in San Francisco, Calif. 

Styles will then hit international cities like New York City, Chicago, Toronto, Paris, a handful of dates in the U.K. and Singapore. The singer wraps up the tour with two stops in Toyko, Japan from December 7-8.

Harry Styles' self-titled debut album drops on May 12 and is executive produced by Jeff Bhaske, the super-producer whose work with Mark RonsonKanye West, and Fun. have scored him GRAMMY nominations. The project features lead single "Sign of the Times" (did you know it's about childbirth?) and "Ever Since New York," both of which he performed on Saturday Night Live on April 15.
