Lately we've been caught in the midst of a seemingly endless array of premieres for sequels, but today we get a breath of fresh air! Katherine Heigl and Seth Rogen walked the red carpet last night for the LA premiere of their new comedy Knocked Up. If you haven't heard about it yet, the movie opens on June 1st and is already being praised by the critics. There were lots of familiar faces including the adorable Paul Rudd and James Franco. Sara Ramirez and Kate Walsh showed their support for their fellow Grey's cast member, and newly engaged Kate showed off her fiance. Not to be outdone, Katherine wasn't shy about making goofy faces with her own fiance, Josh Kelley, and using every opportunity to flaunt her rock.
