Royal christening coming this weekend

LONDON -- The English countryside will be swarming with royal watchers this weekend, all hoping to get a peek at Princess Charlotte when the 2-month-old daughter of Prince William and Kate Middleton is christened.

It will be a royal celebration to remember, with the littlest princess set for her first official engagement in the same gown Prince George wore.

And while Sunday will be Charlotte's day, Prince George taking a backseat to his sister, the fourth in line for the throne now filling an even more important role -- big brother.

In a poignant tribute to Princess Diana, Charlotte will be christened in the same church where her late grandmother was baptized. Princess Diana's favorite photographer, Mario Testino, is tapped to take the

family photo album. But still up in the air is who will serve as Charlotte's Godparents.

And it wouldn't be a British celebration without a bit of tradition d the queen hosting an intimate tea party after the ceremony for William and Kate' s closest friends and family.
