The singer however said that she was also preoccupied with motherhood whilst penning her new album Havoc and Bright Lights, following the birth of her son Ever Imre in 2010.
She told Rolling Stone: "To be honest, I wrote it post-partum the whole few months after my son was born, so I barely remember the process [laughs].
"It was in our home, and we built a makeshift studio in what is now the playroom because I'm an attachment parent, so I wanted to be able to breastfeed. So it was literally in and out of this room, writing with Guy Sigsworth, recording, being a mum, back and forth in my house."
She added: "I barely remember it and I wouldn't say I was letting loose, but I was having fun."
Describing the record, she continued: "There is a lack of apology for the kind of person I am. I used to have some shame around my Ph.D, psychological part and shame about being spiritual, or shame about being emotional or sensitive.
"And what I know now, or what I feel now, is that I don't have shame for those parts. It might p*ss people off or rub them the wrong way or have them roll their eyes. I don't care."
Havoc and Bright Lights is out on August 27, preceded by her new single 'Guardian' on May 15.
