The 2013 Sports Illustrated Swimsuit issue may not be in your mailbox just yet, but we already know it's going to have a heavy dose of Kate Upton. The busty blonde blew up after last year's cover and is continuing her hot streak two years in a row. This is a great day for mankind, perhaps we can even cast aside our differences and find some peace in moment of Kate Upton glory.
This year's issue is expected to come out next week and marks the magazines 50th year.
