StyleList readers disapproved of the mohawk Rihanna was spotted wearing late last week, but did the singer's creative coiffure spark a celebrity trend? Yesterday this photo of Demi Moore sportin' her own punk rock 'do had the Twitterati in a frenzy. Could it be real? Is it for a role? Is Demi just nostalgic for her days as GI Jane?

Demi's mohawk pic photo first appeared on Ashton Kutcher's Twitter account, which you'd assume was a reliable source. But turns out the hair-raising rumor was a fake -- Kutcher was joking (and is surprisingly adept with Photoshop).

The actor posted
: "Wifey just got a new haircut. What do you guys think? I love it."

Apparently sensing a dare, Moore responded within minutes on her Twitter feed: "I have a buzzer ready baby."

Seems like even Demi isn't safe from her prankster husband -- at least she has a sense of humor!

    Victoria Beckham's Pixie
    A significant change from her trend-blazing angled crop of last year, this Spice girl's new 'do softens her features and makes her look less structured, says her stylist, New York's Garren. However, Garren warns that this cut isn't for everyone. An angular face shape, high cheekbones and big almond eyes carry off the striking cut best.

    Reese Witherspoon's Growing Out Bangs

    If you're growing out bangs, look to this starlet's clever new cut to see how it's done gracefully. "The sexy waves are useful for growing out bangs because it adds flowing transition to the different layers of hair. Cut your bangs to an angle so they sweep easily to the side, and use a lightweight gel and side part to help them stay put," advises NYC Salon Owner & Stylist Mark Garrison.

    Jessica Biel's Layered Shoulder Bob

    Jessica's round face is slimmed by the playful layers of an above-the-shoulder bob, which also shows off the star's sexy shoulders. While this cut works beautifully for sweetheart and round face shapes, stay away if you're one of those gals who has to be able to quickly pull her hair into a ponytail; the flyaways can be especially testy.
