Catherine, Princess of Wales, penned a touching letter for guests ahead of the annual "Together at Christmas" carol service, which will be held on Dec. 6 Westminster Abbey.

In recent months, Kate Middleton has understandably been absent from the spotlight…for the most part. We did, of course, get her gorgeous Remembrance Day appearance and we got word of a hush-hush meeting at Windsor Castle.

"Love is the light that can shine bright, even in our darkest times. We all have something we can offer one another," the beloved royal wrote.
