Looks like there's trouble brewing among the royal family. Prince Harry and girlfriend Meghan Markle made a splash during friend Tom "Skippy" Inskip's wedding to Lara Hughes-Young in Jamaica last weekend. Unfortunately, the attention surrounding the new couple did not bode well for Harry's sister-in-law, Pippa Middleton, who's expected to marry James Matthews. According to the Daily Mail, pals of Middleton are speculating whether she will enforce a "no ring, no bring" policy.

Middleton is due to wed the hedge-fund manager on May 20, 2017, and according to friends, the little sister of Kate Middleton is planning to keep the number of guests to a minimum by giving a plus-one only to guests who are either engaged or married. Royal observers previously alleged that Middleton would make an exception for Markle, who's been dating her bro-in-law for a little over six months. Unfortunately for the new couple, Skippy's wedding has seemingly caused Middleton to change her mind.

"She saw how all eyes were on Meghan rather than Lara last week," a friend of Middleton told the Daily Mail. "The situation was also stressful for Harry. Pippa and her mother, Carole, wonder whether Meghan’s presence could cause a great deal of unnecessary chaos."

Afraid of Markle possibly stealing her thunder on the big day, Middleton has since considered not extending a late invitation to the brunette beauty. Sorry, Harry.

Middleton and her longtime love were engaged over the summer, after Matthews popped the question at the Lake District. Her vintage engagement ring is quite the stunner and features an octagonal-shaped halo. The couple will wed at the St. Marks Englefield in Berkshire, and for the reception guests will travel seven miles to Carole and Michael Middleton's home in Bucklebury, where they are set to host the celebration in a luxury marquee in the garden. Middleton's sister will not be a bridesmaid—sad face—but she'll likely do a reading at the ceremony.
