Is Pippa Middleton heartbroken? The royal in-law cancels plans after break-up

Yes, Harry, Pippa Middleton is single once again.

Unfortunately, the royal-adjacent beauty is not exactly ready to mingle. Duchess Kate's little sister has bowed out of a major society event, the Square Mile Masked Ball, in the wake of her break-up from long time love Alex Loudon.

"Pippa was set to attend the Square Mile Masked Ball on November 25th yes but sadly is no longer attending," a spokesperson tells Us. "They heard from Pippa last week. She and a guest were due to attend but ball organisers heard the plans had changed on Thursday."

According to a source, "Pippa's been making a few alterations to her social calendar. It looks like she's trying to keep a low profile -- which is a bit of a change."

Won't somebody think of the designers!? If Pippa isn't making the social rounds this holiday season, that's a whole lot of dresses that won't be getting displayed. The tragedy of it all!
