How to Make Face Look Rounder?

I have a heart shaped face, with quite a narrow jaw line, high and wide cheekbones and kind of a big forehead. I really like my cheekbones but I think I will look better if my face looked rounder! any suggestions, mainly haircuts/styles please. Some celebrity hairstyles that I LOVE are: Nina Dobrev(Elena Gilbert on Vampire Diaries), Blake Lively(Sisterhood of The Traveling Pants, Gossip Girl), Lucy Hale(Pretty Little Liars), and Kristen Stewart, but ONLY in the first and last movies! and not in real life!

Also no makeup, or makeup?
Thanks!

Im not sure about hairstyles but one thing you could try is the opposite of bronzing or sculpting your face. Take a blusher that's lighter than your skin color and apply it below the cheekbones and the jawline. Remember to blend well. Also remember: anyplace you want to bring forward, apply light color; anyplace you want to move backwards, apply a darker color.
