The former Pussycat Doll said that they like to co-ordinate so that their outfits work together.
She told People magazine, “As far as Paula and I, we will find out what colour each other’s dresses are that day and try to wear things that will complement each other.”
And at 33, the singer admitted that her fashion tastes have changed in recent years.
“My style has evolved into being a little bit more grown up. It’s rock ‘n’ roll inspired, but chic. Glam rock.
“If I wear a lace dress I throw on a leather jacket to toughen things up, or some crazy boots. I like dresses that are sassy, but have clean lines.
“I want to wear dresses that make me feel like a woman, but I add a rock edge to it as well. That’s my style and I’m an artist before I am a judge.”
Having dieted for so many years, Scherzinger said that her slim figure is now down to dancing, running, sleeping well, drinking water and a balanced diet.
“I’ve gone through so many years of diets, that now I don’t deprive myself of anything,” she said.
