You can watch "The Kardashians" for free if you sign up for Hulu's free trial. Hulu offers a 30-day free trial for new subscribers. If you sign up now, you'll be able to watch all the episodes released over the next 30 days as they're added to Hulu. However, it's not clear exactly when the season two finale will air just yet, so you'll have to wait if you want to watch the entire second season for free.
