Pippa Middleton prepares to walk down the aisle

A small English village is under siege as Pippa Middleton prepares to walk down the aisle and marry her millionaire fiancé James Matthews.

The event has Royal watchers wondering who will steal the show?

Will it be the bride or her sister The Duchess, young Prince George and Princess Charlotte or their Uncle Harry and his actress girlfriend Meghan Markle?

The tiny hamlet of Englefield is getting a last minute once over before it plays host to a traditional English church service that's going to receive worldwide attention whether the couple likes it or not.

"They will have a fantastic time, I don't know the full ins and outs of their wedding, but I'm sure they'll have a good time," Mike Tindall said on Good Morning Britain.

While Pippa gained global fame helping her sister carry her very long train, The Duchess of Cambridge doesn't have an official role at today's wedding, but Prince George will be a page boy and Princess Charlotte will be a bridesmaid.

The venue is a 12th-century chapel, not far from where the Middleton girls grew up.

"Pippa's a great girl, it's fabulous to see her, she's handling herself really well I believe."

And while it's her special day, not all eyes will be on the bride.

One woman revealed who she'll be watching, "Prince 'Georgess' as we call him in Wales. George-ous and his little sister."

Another said they will be looking for Harry and Meghan Markle - the prince's American actress girlfriend, expected to make her official "Royal debut" on the arm of her prince.

The tabloid papers are already speculating whether Meghan's posterior will gain attention just like Pippa's did during the royal wedding.

The reception will take place under an enormous glass marquee, imported from Belgium and constructed on the Middleton family estate.

It's sure to disappoint the paparazzi as they can't get anywhere near it.
