Hollywood has a real thing for the choppy bob. Among fans of the layered look are Scarlett Johansson, Nicole Richie and Olivia Munn, who just showed off her uneven cut at a photography exhibit in NYC last week.

While we appreciate the fresh update on this formerly sleek style, it's also the kind of thing that could spark a DIY (do-it-yourself) trend with drastic results.

It might look like these seemingly low-maintenance stars are hacking off their own locks in front of their bathroom mirror but just like anything else in La La Land it probably took hours (and a pricey stylist) to sculpt this bedhead style just right. So as with anything else you see on TV,  go with a pro and don't try this at home!
