Jennifer Lawrence just made it official: The hot new hairdo for fall is definitely the pixie cut!

The 23-year-old 'Hunger Games' actress is only the latest female celebrity to show off her take on the dramatic short 'do (following the likes of fellow Jennifers Aniston and Hudson) -- but considering her age, Academy Award and way with a quote, she's probably the coolest.

J. Law posted a pair photos showing her haircut on her Facebook page today (Nov. 6). The pics were taken while she prepared for a global Google+ Hangout celebrating upcoming sequel 'The Hunger Games: Catching Fire.' Here she is adorably trying on Google Glass:

West Hollywood stylist Riawna Capri gave Jennifer the cut and color a few weeks ago, a source tells Us Weekly. Another source describes the 'do as "kind of a punk pixie cut that has a few longer pieces on one side but is shorter everywhere else."

Jen attended the Google+ event with hunky co-stars Liam Hemsworth and Josh Hutcherson, but we think everyone might have just been staring at her hair.
