Gwyneth Paltrow Sends Message to Kate Middleton Following Royal Appearance

Gwyneth Paltrow is showing her support for Kate Middleton following the royal's first public appearance since revealing her cancer diagnosis.

Over the weekend, the 42-year-old princess attended the Trooping of the Colour alongside her husband, Prince William, and their three children. The Saturday, June 15, event marked the Princess of Wales' first royal outing in six months and her return to the public eye saw quite the commotion from fans–which apparently included the 51-year-old actress.

The official Instagram account for the royal couple uploaded a carousel of photos that featured nearly a dozen images from the event, including shots of the princess standing beside her husband of 13 years, their kids–Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6–as well as her in-laws, King Charles III and Queen Camilla.

"A memorable day at The King’s Birthday Parade. From the Irish Guards Trooping their colour to seeing so many faces on the Mall, thank you for making it a day to remember. ???," the accompanying caption read.

The Goop founder sweetly replied back with a message aimed at the princess. "So happy to see you looking so happy and well??," she wrote.

Days before this year's big parade event kicked off, Kate wasn't expected to attend as she's still undergoing treatment for an unspecified type of cancer she was diagnosed with earlier this year. The proud mom of three even apologized for missing the rehearsal.

The pleasant change of plans, however, was announced in the final hours leading up to the King's Birthday Parade and two days after Kensington Palace officials went on the record with a rare update regarding the princess' treatment.

While many of the other royals find themselves fully booked with engagements throughout the summer, Kate's plans have not been publicly revealed, and rumors suggest she's decided to prioritize time with her family before making an official return to her royal duties.
