James popped the question to Prince George and Princess Charlotte's aunt in England's Lake District. Before getting down on one knee, Pippa's hedge fund manager beau reportedly asked her parents, Michael Middleton and Carole Middleton, for permission to marry their daughter.
"They make a wonderful couple and we wish them every happiness together," Michael said in a statement on Tuesday, July 19. Pippa and James reportedly first began dating less than one year ago following the author's October 2015 split from boyfriend Nico Jackson.
