According to the Wall Street Journal, two young stars have the hottest haircuts of the year: actress Emma Watson and singer Justin Bieber. The paper has dubbed their hairstyles the "Most Influential" of 2011.

“Hairstylists are being inundated with requests for pixie cuts and the Bieber swish,” the WSJ notes. (As you can see in the photo above, though, Bieber doesn't even have the "Bieber swish" anymore - he cut his hair in February.)
Nonetheless, the paper continues, “The enthusiasm plays out online, where the fastest-rising searches for celebrity haircuts on Google are for Ms. Watson and Mr. Bieber.”According to the Journal, Watson’s cropped cut is particularly notable, since for women, “short hair hasn’t been trendy since the ’90s.” Currently, celebs like Michelle Williams, Halle Berry and Pink are also rocking the pixie.
The WSJ names other fashion highlights from 2011, including the Royal Wedding (deemed the “Fashion Event of the Year”); Kanye West’s Paris Fashion Week debut (the “Biggest Runway Flop"); and Target’s in-demand Missoni collaboration.
