Former Pussycat Doll Nicole Scherzinger has revealed that her time with the band was lonely as "nothing was ever good enough."

The 35-year-old singer told The Guardian, "My 20s were fruitful but not enjoyable. Being in The Pussycat Dolls was probably my loneliest time because I was quite insatiable.

"Nothing was ever good enough and I didn't know how to take a break. My 30s have definitely been more chillaxed."
