Princess Charlotte and Prince George will play a starring role in the royal wedding - as a bridesmaid and a pageboy.
Kensington Palace announced that Prince Harry's niece and nephew would be among Meghan Markle's young helpers at the nuptials in Windsor this weekend.
Charlotte, three, and four-year-old George are already skilled in the role, having performed the duty for the Duchess of Cambridge's sister, Pippa Matthews, last year.
The palace announced that Ms Markle would have six bridesmaids and four pageboys.
The bridesmaids include Harry's goddaughters, Zalie Warren, two, and three-year-old Florence van Cutsem, Ms Markle's goddaughters, sisters Remi and Rylan Litt, aged six and seven respectively, and four-year-old Ivy Mulroney.
The other pageboys are Harry's godson, Jasper Dyer, aged six, and seven-year-old twin brothers Brian and John Mulroney.
