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 and decided to continue with her career as a solo recording artist.

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.

Wyatt said "I think ultimately there’s some unfinished business with The Pussycat Dolls"[5] and Roberts agreed, noting that it had "been 10 years ... we just all were ready to do it".

[8][9] The Pussycat Doll Tour's first leg was supposed to begin in April 2020, visiting nine venues around the UK and Ireland, plus an appearance at Fabuloso Pride in the Park (Brighton) in August.

[9] However, by March 2020 the UK was being impacted by the COVID-19 pandemic, leading to social restrictions making the tour impossible to go ahead; new dates were planned for October.

[10] Following the same guidance regarding social restrictions, organisers of Pride in the Park announced the event was being delayed 2021, with the Pussycat Dolls returning to headline.

In September 2021, it was reported that Scherzinger was refusing to take part in the tour and had been subsequently sued by Robin Antin, founder of the Pussycat Dolls.

The media reported that Scherzinger had originally agreed to 49% of the tour's earnings but was now refusing to take part unless this rose to 75% and included overall creative control.
