The Pussycat Dolls Tour (also informally known as The Unfinished Business Tour) was the planned third concert tour by American girl group the Pussycat Dolls. It was announced in 2019, when Nicole Scherzinger, Ashley Roberts, Carmit Bachar, Kimberly Wyatt and Jessica Sutta revealed that they were reforming for new music and a brand new concert tour. Former member Melody Thornton declined to reunite but decided to continue with her career as a solo recording artist. The announcement followed the release of "React", the first new song by the group in more than a decade.
The tour was due to begin in April 2020 with 10 arena dates around the UK and Ireland, but these were postponed until the Autumn and then Spring-Summer 2021 due to the worldwide COVID-19 pandemic. It was then scheduled to begin on May 21, 2021, with ten dates across the UK and Ireland. A number of festival dates were cancelled all together including a headline slot at Brighton Pride (UK), So Pop Festival (Australia and New Zealand), Untold Festival (Romania), and Superbloom Festival (Germany), while some international dates in Japan, Brazil, and the Philippines were postponed pending further confirmation. Following further delays which were down to the pandemic, breach of contracts and logistics, the tour was ultimately cancelled in January 2022 with the fate of the Pussycat Dolls unknown pending the legal dispute between Scherzinger and Antin regarding the terms of the group's business ventures.
