Five of the group's original six members - Nicole Scherzinger, Ashley Roberts, Kimberly Wyatt, Jessica Sutta and Carmit Bachar - have reunited and the group will be embarking on a United Kingdom and Ireland arena tour, their first in 10 years, starting in April 2020.
The "Don't Cha" singers will also go on a tour of their own after an nearly 10-year hiatus, with them taking their break from each other back in 2010.
"L.A. was our home, but the United Kingdom was our second home because the British just scooped us up", she said.
"I've been working on making this reunion happen now for years, so I am very excited that the stars have aligned for THE PCD REUNION!"
This is the beginning of what we imagine to be an incredible reunion tour, and we can not wait to see what other dates the girls release! Nicole had been in two groups prior, she had a lot of experience.
The singer confessed she was suffering from bulimia and did not feel able to open her bandmate.
But nine years later, lead singer Nicole has said they've "grown so much" since then. "The Pussycat Dolls are the special guests!" he told Lorraine Kelly during a live TV interview on Monday. When you're battling your own demons and insecurities, it's not something you want to share with other people. "After he said it, he was like 'did I just drop the ball?'" And it was this apology she began on the path to healing that culminated in this reunion journey.
"I created The Pussycat Dolls back in 1994 and never in my wildest dreams would I have thought it would become one of the most iconic girl groups of our time".
Melody Thornton is the only member of the girl band not coming back for the tour, although it is not now clear why.
As for Carmit Bachar and Melody Torten, ET reports that Bachar has confirmed to them that she will in fact be returning for the reunion.
"Like any family, it's a relationship and you can do it", Nicole added, seeming confident they could get there. But we always had so much respect for each other.
Now the women see this reunion as an opportunity to spread a stronger message and be an inspiration to other women, and describe the current #MeToo climate as a "beacon for empowering women".
The Pussycat Dolls, who have sold more than 54 million records around the world, plan to launch their reunion with a performance during Saturday's The X Factor: Celebrity final, followed by a tour next year.
While there is no date for the show just yet, the tour will kick off in the United Kingdom in April 2020.
"We're focused on the tour right now and ... stretching", said Scherzinger, who in recent years has regularly appeared as a judge on British talent show "The X Factor".
