The 31-year-old `Your Body` singer - who recently lashed back at critics of her curvier figure - has insisted she has no fear of getting older and finds it liberating.
The mum-of-one told People.com: "Some people are afraid of change and [feel] that getting older is a bad thing, but I really love maturing and gaining wisdom.
"And the experience of being pregnant and having a child and seeing what a woman`s body can do is amazing."
`The Voice` judge also claimed she has no problem ignoring her critics because she is very comfortable in her own skin.
She said: "I`ve always been one to make it very clear, love me or hate me, take it or leave it, this is who I am.
"I embrace my body, and I embrace everything about myself. Coming full circle is a celebration of freedom and happiness because that`s what [my new album] `Lotus` is representing. I`m embracing everything that I`ve grown to be and learned to be."
The singer appears naked on the cover of her new album - set to be released on November 13 - because she didn`t want to make a fashion statement.
She said: "It`s very interesting, because I don`t see that album cover as being nude at all.
"I actually feel very covered and it`s all about embracing white light and freedom, and I didn`t want it to be about too much fashion. I wanted it to be raw, real and free and a celebration of life and the woman I`ve become."
