Check Out These Awesome Celebrity Mash-Ups

At first glance, these celebrity portraits look legit... but maybe a little off. That's because Photoshop guru Gesichtermix took two real celebrity portraits and merged them into one pretty lefit image.

Some of thee standouts from these celebrity mash-ups include Justin Timberlake/Justin Bieber, Jennifer Lawrence/Claire Danes, Shaquille O'Neal/50 Cent, Rihanna/Katy Perry, Pharrell Williams/Channing Tatum, and Jennifer Lopez/Halle Berry.

See if you can guess the others.
