Back in 2017, Pippa Middleton and James Spencer’s wedding stirred up some controversy for a few reasons.

Not only did her mother Carole — who’s also Kate Middleton’s mom, the Princess of Wales — have to issue a formal apology because of a major disruption that night, but guests Prince Harry and Meghan Markle were kept apart throughout the entire event.

So, let’s start with the first “inconvenience,” shall we?

Just as a quick refresher, Kate’s younger sister Pippa got engaged to James Spencer, a former British professional racing driver and businessman, in 2016, after he proposed during a trip to the Lake District.

(This was also the same year Harry and Meghan, the ex-Suits actress, publicly confirmed their relationship — but that part will come up later…).

One of the most talked-about parts of the wedding was the disruption the afterparty caused to the Middleton family’s neighbors.

The ceremony itself was held in May at St Mark’s Church on the Englefield Estate in Berkshire. Afterwards, Pippa and James hosted their reception at the Middleton family’s former home, Oak Acre, which sits on an impressive 18 acres of land.

However, the huge celebration brought nonstop noise from cars coming and going throughout the day, plus a surprise fly-by by a Spitfire plane.

Because of this, Pippa’s mother Carol had to apologize in advance for any “inconvenience” the event might cause, according to HELLO! magazine.
