Nicole, 35, said that her style is completely different from younger sister Sofia's and that is why she never gives her any advice on the same, reported People magazine.
"I'm very particular about my clothes. We (me and my sister) have different styles. I don't know if I've given her any (style advice)," Nicole said.
The one area in which the popular TV personality, who has kids- Harlow, nine, and Sparrow, seven, with husband Joel Madden, could offer an advice, is on having healthy hair.
