Just as the Princess of Wales’ decision to bring only daughter Princess Charlotte to Wimbledon with her this past Sunday was a significant one, so was Kate’s decision to have her younger sister, Pippa Middleton Matthews, by her side, as well.
“They were already genuinely best friends, but this grueling year has seen them grow even closer,” a source told The Daily Express. “Pippa has been something of an angel and backbone for Catherine. She’s there at the drop of a hat, helping to pick up the slack on physical tasks when needed. But it’s the emotional support she provides that is invaluable to Catherine.”
