During an appearance on the podcast Private Parts, Ashley revealed that she was rushed to hospital at the height of the bandâ€™s fame, with doctors fearing she was suffering from a brain aneurysm.
â€œThe thing was, being in a girl band, we made people a lot of money so the schedule was outrageous,â€ she explained.
â€œIâ€™m not going to lie, by the end I was breaking down. I was in the hospital. They thought I was having a brain aneurysm.â€
Ashley continued: â€œI think it was just from going, going, going and my body was just shutting down really.
â€œI remember being in the hospital, I was actually here in London, and I was like, â€˜Iâ€™ve got to go to Germany, Iâ€™ve got to get on a plane nowâ€™. I was like, â€˜Iâ€™ve got a show to doâ€™.
â€œAs I was walking to get the MRI because they thought I was having a brain aneurysm, my knee locked up and I got this viral arthritis so I couldnâ€™t bend my knee. The doctor was like, â€˜I think you need to just restâ€™. Itâ€™s wild.â€
Despite the challenges of being part of the Pussycat Dolls, Ashley has also spoken about the emotional impact of the bandâ€™s split.
â€œWe were on the road for eight years pretty much solid, and then spat out the other end,â€ she added. â€œAnd I was like, â€˜Who am I without this identity in the group?â€™.â€
After originally starting out as a successful burlesque troupe, the Pussycat Dolls launched their music career in 2004, with their breakthrough hit Donâ€™t Cha being released a year later.
In the years that followed, the band scored hits with Stickwitu, Buttons, When I Grow Up and Jai Ho!.
In 2019, the band announced a comeback, including the release of new single React, which they debuted during a provocative medley performance in the X Factor Celebrity final, sparking a flood of Ofcom complaints in the process.
