A new leg of his Together, Together tour has been confirmed, adding twenty-five performances to the existing schedule.
Three of these shows are scheduled in London, while the majority will take place in the United States.
The American dates include venues in Phoenix, Dallas, Atlanta and Chicago, marking Styles' debut at US stadiums as a solo artist.
Support acts vary by location, with Tears For Fears appearing at Wembley and Kylie Minogue headlining in Los Angeles.
Minogue's participation in the California show will be her first ever stadium concert in the country.
The tour follows a period of high demand, with nearly one million people attending previous performances at Wembley Stadium.
Tickets for the new dates are priced between $60 and $300 (£44 to £221), depending on the city.
A limited number of discounted passes will be available for £20 in the UK, $20 in the US and €20 in Europe.
Full details regarding sale times and booking methods can be found on the artist's official website.
Styles is currently occupying Madison Square Garden in New York with a thirty-show residency.
He has also announced additional stops in Ireland, Spain, Italy, Germany and France for later in the year.
Those who missed the initial summer run are encouraged to check availability soon as more information will be released shortly.
