Of course, the children's parents, Prince William, 34, and Duchess Kate, 35, — Pippa's older sister — will also attend the ceremony, as will their uncle, Prince Harry, 32.

Prince William may even have flashbacks of his own time as a dapper little page boy.

William was just 4 years old when he took part in the 1986 wedding between Prince Andrew and Princess Sarah "Fergie" Ferguson.

It's not yet clear what role Duchess Kate will have in the wedding party of her only sister, but we're expecting it to be a high profile one.

Matthews, a hedge fund manager, proposed to Middleton last year.

The couple will marry at St. Mark's Church, Englefield, about 50 miles outside of London, on May 20.
