The 41-year-old singer has only recently unveiled her deep interest in psychology and spirituality, and is currently working on a book that is half memoir and half "reflections, insights, regrets, and just straight-up teaching", reported Vogue magazine.
She also regularly keeps her fans updated with her progress in life through her blog and Instagram feeds, and admits that these methods of sharing have proved eye-opening for her.
"I've always had a little of a blind spot around how I am perceived. But there's uniformity now. This may be a crass way of understanding it, but there's something about even looking at my own Instagram, looking at my blog, where I'm getting a sense of self that I never had," she said.
