Watermelon Sugar hitmaker Harry Styles has joined forces with sleeping and relaxation app Calm, lending his voice to one of its 'sleep stories', Dream With Me, following in the footsteps of fellow story readers Stephen Fry, Kelly Rowland and Matthew McConaughey.

The British singer/songwriter said of the collaboration 'Sleep and meditation are a huge part of my routine, whether I’m at home, in the studio, or out on the road. Rest and recovery is as important as doing the work'.
