Nicole Scherzinger "got back to her authentic self" following her split from Lewis Hamilton.
The former Pussycat Dolls star enjoyed learning about herself again after she split from the Formula One racing driver.
She told Glamour magazine: "I got back to my authentic self. It was, oh, this is what I like and this is what makes me laugh and what makes me dance and feel free. It was a transformative, healing time.
"It's so important as women, whether we're in relationships or not, that we nurture ourselves. You have stronger relationships when you're strong within. When you're not looking for somebody else to fulfil you."
Meanwhile, the 38-year-old singer - who is now happily dating tennis player Grigor Dimitrov - previously insisted she isn't feeling broody because she has such a big family.
When asked if she feels broody, she said: "No because I literally have the biggest family in Hawaii and they're popping out kids every day. For me, all that will come in its own time ...
"I feel like God put me on this earth to create something really great and to share whatever gifts he's given me, whether that's music or helping people. I feel I have to be smart and take my time with my next project and my music, because it's got to speak and stand the test of time. But I can't wait to get married and have kids, it'll be awesome."
Nicole likes to keep her personal life private but recently revealed she is very happy with Grigor.
She said: "We've been together for quite some time now so I'm just living in the moment and I'm happy."
However, Nicole only knows too well how relationships can "suffer" as a result of her work.
She added: "I have missed out on a normal life, because it is a sacrifice when you put your heart, your time and everything into a job. Relationships suffer."
