Jennifer Lawrence and Minka Kelly's big hair week

Actresses are making bold hair changes right and left these days. First we had Sofia Vergara debuting a freshly highlighted and lightened up mane. That was followed by Reese Witherspoon showing off her new brunette hue. But Tinsel Town's ladies were making more hair-raising headlines this week. Jennifer Lawrence showed up at the GLAAD Media Awards with a newly cropped 'do that hit right at her shoulders while Minka Kelly revealed a softer, lighter version of her signature long locks. I think both looks are totally of the moment and show off each girl's fashionably fearless side. What do you think? Whose makeover do you think works better?
