Ever since co-writing Rihanna's Hot 100 No. 1 "Work," PARTYNEXTDOOR has been getting some big pop songwriting gigs. This year, he's appeared on Zayn's "Still Got Time" and Major Lazer's "Run Up," and he's now signed on to a tour which echoes those crossover aspirations.

PND will serve as the special guest on Halsey's upcoming Hopeless Fountain Kingdom World Tour, which will also be supported by Charli XCX. The tour kicks off in September, and will take the three artists throughout the U.S. and Canada.

Knowing PND's reputation, he'll be writing while he's on the road. Maybe we can expect some collaborations with his tourmates?
