Pippa Middleton alters her 'no ring, no bring' rule to include Meghan Markle

We're just ten days away from Pippa Middleton's highly anticipated wedding. Duchess Kate's younger sister is set to marry James Matthews on May 20 in Berkshire, England, near the Middletons' hometown. And yes, many of the royals are expected to attend, including her niece, Princess Charlotte, and nephew, Prince George.

The 33-year-old bride-to-be is gearing up for her big day by dieting, exercising -- and apparently, by fine-tuning her guest list. She's reportedly implemented a strict guest list for the high-profile wedding, including a "no ring, no bring" rule for unmarried attendees.

How would the new rule play out for Prince Harry and his girlfriend Meghan Markle? It was initially reported that Markle would skip the wedding ceremony and join the rest of the family at the reception, which is expected to be less formal.

However, a new report suggests that Pippa has made an exception to include Markle in the nuptials! According to E! News, the "Suits" actress has been busy shopping for the big day, which includes buying a traditional hat for the festivities.
