Her Royal Majesty was all smiles on Tuesday, hosting a Garden Party at Buckingham Palace, just four days before her grandson, Prince Harry, will say "I do" to Meghan Markle at St. George's Chapel.
The 92-year-old royal looked ravishing for the annual soirée, stepping out in a robin's egg blue-colored jacket, which she paired with white gloves, black loafers, pearl jewelry and extra stylish sunnies.
She topped off the look with a matching hat, flashing a big grin as photographers snapped her pic.
The appearance comes amid all the drama surrounding who will walk Meghan down the aisle at her upcoming nuptials on May 19. There's a chance the former Suits star's father, Thomas Markle, will still do the honors, following reports that he would no longer be attending the nuptials after he was accused of staging photos for the paparazzi. A source told ET that Meghan was "devastated" when she heard he would no longer be coming, but according to a new report from TMZ, Thomas has changed his mind and is hoping to be there.
ET spoke with royal expert Katie Nicholl on Tuesday, who tells us that all the recent drama is "madness."
"There is so much confusion, there have been so many mixed messages," she explains. "I mean, frankly, this is not how we do royal weddings."
"[Queen Elizabeth II] is hosting one of her many annual Garden Parties. I'm sure no one wants to upset the queen by mentioning the whole Thomas Markle debate," she continues. "Who knows whether she has been updated with the latest [news]."
Nicholl also tells ET that she spoke with Kensington Palace before our interview, but "apparently no changes were made to the order of service," which originally stated that Thomas would be walking Meghan down the aisle.
"I think it would be a bit of a giveaway had they reprinted or changed the order to reflect the fact perhaps Thomas Markle wasn't coming," she says. "I was told that Meghan had been in 11th hour talks with her father [last night]. They had quite a few conversations late into the night, with Meghan really pleading with her dad, telling him that this didn't matter, they can get over this, but she really wanted him to be there for her special day. And I guess the 'Please, Daddy' -- it worked."
"I was told by sources close to Meghan last night that she was utterly heartbroken that she couldn't believe that this was happening just days before her wedding," she adds. "That she is close to her father, they always had a special relationship, and that she feels that what he did in terms of staging those photographs were never meant with a cruel intention -- it was actually meant to present himself in a more positive light. He didn't ever have any understanding or any suspicions that this could have backfired on him as badly as it has done."
ET has reached out to Thomas for comment.
