Development
On October 26, 2017, Lovato first announced she was going to tour in 2018 with a special guest. Later that day, she revealed the special guest was DJ Khaled. During the American Music Awards 2017 backstage, Lovato announced that American R&B singer Kehlani would be joining Lovato and Khaled on the tour as the opening act. In an interview with Billboard, Lovato revealed the reason she chose the opening acts was that Kehlani inspired Tell Me You Love Me and DJ Khaled was "much fun to watch". Lovato announced on Good Morning America that her co-owned mental health program CAST Centers would return to join her on tour to provide free therapy sessions and wellness workshops after joining their co-headlining Future Now Tour in 2016. The session also featured guest speakers, including Lovato herself, DJ Khaled in Las Vegas date, Iggy Azalea during the Brooklyn stop, Kelsea Ballerini in Nashville and Lauren Jauregui in Miami.
On February 12, 2018, Lovato revealed the European tour dates, which were scheduled to start in May 2018. This marked the singer's first European concert since a festival appearance during the French NRJ Music Tour in 2015. Three days later, on February 15, 2018, Latin American dates were announced in Brazil, Argentina, Chile, Ecuador, Costa Rica and Mexico. The Panama City date was announced on March 7. They were expected to take place in April and early May, but due to production issues, Lovato announced on April 10 that eight dates of the leg in Latin America were rescheduled, while the planned shows in Panama, Ecuador and Costa Rica were cancelled. Additional dates in Amsterdam, Belfast, Dublin and Newcastle were announced on March 13. Lovato added two festival appearances in England and Wales on April 4 and 5, 2018. On April 6, 2018, Lovato announced a show in Paso Robles, in which Australian rapper Iggy Azalea would join her as the opening act. On May 8, Lovato announced that English record producer Jax Jones would join her in United Kingdom dates as the supporting act. On May 21, it was announced that Lovato would take the stage in Atlantic City, with Lauv as an opening act. On May 23, Lovato announced that Australian singer and record producer Joy would support the European leg. On June 5, 2018, Becky G was announced as the opening act in Argentina and Brazil dates. About being the supporting act, Becky G told Billboard that it would be "awesome" to join Lovato on tour. She later explained that it was their second time being Lovato's supporting act since 2014 Demi World Tour and commented that she learned much from Lovato at that time. Mexican singer Jorge Blanco was announced as the opening act for the Mexican dates. On July 24, after an hospitalization, it was announced that Lovato would not perform at the show at Atlantic City, which was scheduled to take place on July 26. After speculation, on August 8, it was announced that the shows in Chile, Argentina and Brazil were cancelled due to health issues. The next day, it was announced that the shows in Mexico were also cancelled due to the same reason.
Lovato told Billboard that the tour would have "a lot more production". "It will represent who I am as a person and an artist and I can't wait for this country to see it," she added. Lovato also aimed to take an intimate experience on the tour. "I'm going to utilize the arenas and really make sure that from every seat, you get to see my performance up close and personal, as much as we possibly can," she said. Rehearsals for the tour took place at Sleep Train Arena in Sacramento, California.
