Pippa Middleton was spotted visiting St Marks’ Church in Berkshire this week to presumably go over last-minute details for her wedding. The 33-year-old will say “I do” to financier James Matthews on May 20 in the small, quaint country church, located on the privately owned Englefield Estate.

Pippa and her fiancé James were last pictured at the church on Christmas Day, when they attended last year’s service with the Middletons. The ceremony will be officiated by Rev. Nick Wynne-Jones, resident priest at St Mark's. The bride’s sister Kate is on the star-studded guest list, as is her husband Prince William and the royal couple's children Prince George and Princess Charlotte.

Why Scotland could be Pippa Middleton's honeymoon destination

Although it is yet to be confirmed whether the Duchess of Cambridge will be the Maid of Honour on the special day, Kate has been a supportive older sister and was spotted visiting Pippa at her home earlier this month, where the pair may have discussed last-minute wedding day details.

Her children Prince George and Princess Charlotte will act as pageboy or ring bearer, and flower girl, respectively.
