Kim Kardashian's Blond Hair Is "a Great Change" for "Incredible" New Mom, Says Rob's Ex Adrienne Bailon

"I think Kim is going to just be everything North can ask for in a mom," she gushes to E! News exclusively

Kim Kardashian's new blond hair has everyone talking—even her little brother's ex-girlfriend!

Adrienne Bailon, who dated Rob Kardashian from 2007 to 2009, absolutely loves North West's mom's sexy, lighter look. "I think blondes have more fun, so I am excited for her," she told E! News exclusively on Thursday, Sept. 5, at VEVO and Style Network's "Styled to Rock" event in New York City. "She has been a blonde once before [very briefly in 2009], and I think it's a great change. Anything that makes a new mom feel hot and sexy is a wonderful thing!"

But Adrienne doesn't just think Kim's a hot mama—she thinks she's going to be an "incredible" one. "I think Kim is going to just be everything North can ask for in a mom," she gushed.

Little Nori "is stunning," the former Cheetah Girls star added. "She looks just like Kim when she was a baby."

Hey, those Ks have good genes!
