With just a few days until her younger sister’s wedding, the Duchess of Cambridge expressed her excitement for Pippa Middleton and James Matthew’s highly-anticipated nuptials. While at the first Buckingham Palace garden party of the season on Tuesday (May 16), Kate chatted with partygoer Andrew Bates and his wife Janet about her sibling’s big day, admitting that she is looking forward to the wedding, but is slightly nervous about how her young children, Prince George, three, and Princess Charlotte, two, are going to behave.

“[Kate] said that they were all really looking forward to her sister's wedding at the weekend but she was a bit worried about how her children might behave," Andrew revealed. "She said she was hopeful that they would be good but you never know at that age.”

It was previously announced that Prince George and Princess Charlotte will serve as a pageboy and bridesmaid in their aunt’s upcoming wedding. Pippa and her fiancé are set to tie the knot on May 20 at Mark’s Church in Englefield, Berkshire, followed by a reception at the Middleton family home in Buckleberry, seven miles away from the church.

Kate opened up about her sister's wedding during a garden party at Buckingham Palace on May 16.

While Saturday will be a family affair for the Duchess, Tuesday was business as usual for the British royal. Kate looked sophisticated at the May 16 party stepping out wearing her ice blue Christopher Kane coat dress, which she previously wore to the Opening Ceremony of the 2012 London Olympics and again in 2014 for the Order of the Garter. The mom-of-two opted for an elegant updo, which she topped off with a pale blue Lock & Co "Sweet Delight" hat.
