Katherine Heigl and her Life As We Know It co-star Josh Duhamel were more than just excited to be attending the world premiere of their film in NYC on Thursday — they were downright giddy! But when you have a co-star like Josh Lucas and Katherine's husband Josh Kelley at the event, it's more of a party than a premiere!
