Prince Charles had quite the Monday at Buckingham Palace as the Royal family came together to honor his 50th anniversary as Prince of Wales. Duchess of Sussex Meghan Markle glowed as she held on to husband Prince Harry and her adorable baby bump, joining Prince William and Duchess of Cambridge Kate Middleton for the special occasion.

At the age of nine, Prince Charles was made Prince before being formally inducted 11 years later at Caernarfon Castle, making him the longest-serving Prince of Wales in U.K. history.

Markle stunned for the reception in a cream-colored coat, a metallic dress, and pink heels. Middleton, meanwhile, was more demurely dressed in a mint-colored gown that had ruffled sleeves and a button-up collar, which she paired with suede nude heels.

This is the first time Middleton and Markle have been spotted together since late last year. They were last seen together during a public engagement on Christmas Day amid reports that the two were secretly feuding.

And while Prince Harry has tried to protect Markle from bad press, a source told Us Weekly that he is disappointed that he hasn’t been able to do much about the way his wife has been portrayed in the media.

“Keeping her away from the negativity and harm has been hard for him. It’s been his purpose in their relationship to keep her away from the negativity.” The insider continued, “it has put pressure on her relationship with Harry. He’s very frustrated with how little can be done.” But all seemed well as the Royals gathered to celebrate Prince Charles.
