Now that you've cast your votes on favorite trends, footwear designer, and online shopping fun, it's time to turn your attention to the Fab celeb couples of the year. Here at Fab, we've got a few power couple crushes, but it's always hard to narrow it down to just one standout. For 2010, we're nominating Olivia and beau Johannes for their impeccable chic, Diane and Josh for their always-cool style, and Gwen and Gavin for a signature rocker edge. Jay-Z and Beyonce also deserve a nod as a glam duo of the year; Katy Perry and new hubby, Russell Brand keep things fresh and fun, and the Beckhams keep things stylish, whether event hopping or hanging with the kids. It's a tough call, but it's in your hands. Click through to see the nominees, then vote for the most stylish couple of the year!
