It's the battle of the bottle blonds!

This summer tons of dark haired celebrities lightened their strands and now it's time to pick our favorite Goldilocks in Hollywood.

First up? Kim Kardashian, of course! The E! star debuted her new mom look over Labor Day weekend. While this is the second time she's gone blond, her latest version is a much more modern take with the dark roots.

Also going with an almost ombree effect, Vanessa Hudgens lightened the lower half of her strands leaving the top brunette. Selma Blair stepped out with a similar style, at first, then a few days later she showed off a completed blond 'do.
