The former X Factor judge, 36, says that writing her new album Big Fat Lie was like "therapy."
"It's a very personal album to me," she told the Evening Standard. "It's a transitional album, and it's very honest and authentic."
Scherzinger also opened up about her eating disorder, which she first revealed in a candid 2012 interview. For eight years, the singer said she felt like "I wasn't enough, that I wasn't pretty, that I was fat, and that I wasn't worthy of more."
But that was then.
"I'm in a different place in my life now," she says. "I feel a bit more confident and comfortable in my own skin to be able to talk about things that I hadn’t talked about before."
The former Pussycat Doll hopes people can relate to the honesty on her album, to be released in 2015.
“It feels good to be truthful, because not everyone’s perfect," she says.
Nonetheless, she notes, "Everyone always has these pre-conceived notions that you're glamorous, you don't have any problems, you don't have any issues, and we all battle with our own issues."
