"After lengthy conversations, they've taken what they call a 'permanent break,'" one insider close to the couple tells Us. Duchess Kate's little sister met Loudon, a 30-year-old cricketer turned finance whiz, on a blind date set up by mutual pals.
"They hope to stay friends," adds a second source. "They're doing their best to move on in a dignified manner."
How is the handsome ex taking the news? "Alex is upset but getting on," a friend tells Us.
Although social butterfly Pippa has seemingly relished her newfound spotlight, Loudon's "life was turned upside down" once he was the outgoing, ever-stylish maid of honor's date for the royal wedding on April 29, his pal says.
Even before the reported breakup, Middleton set tongues wagging over her wedding-day chemistry with Prince Harry (who's happily ensconced with love Chelsy Davy) and recent bonding time in Madrid and London with close friend and co-worker George Percy.
