Fergie dyed her hair brown to help her "evolve" into an adult.The Black Eyed Peas singer has revealed she swapped her blonde tresses for glossy dark locks earlier this year because she was married and wanted to look "more mature".
The 34-year-old star - who wed 'Transformers...' star Josh Duhamel in January - said: "I've always been blonde, but it's a new time in my life. It felt like it was time to evolve."
Suddenly, seeing little girls in the audience with their mothers made me think about what I do on stage a bit more. I had to watch my mouth, because it can be filthy. It changed things for me.
Fergie has also stopped wearing revealing outfits to enhance her new "serious" image and claims it is being love which inspired her transformation.
She explained: "I've been in a lot of relationships that were exciting but unhealthy. I wanted somebody that I could count on. With all the craziness in the business, I know I can count on my man - and he knows he can count on me."
The couple don't yet have any children, but Fergie has already changed the way she behaves in preparation for motherhood.
She added: "Suddenly, seeing little girls in the audience with their mothers made me think about what I do on stage a bit more. I had to watch my mouth, because it can be filthy. It changed things for me."
