The royal fab four are together again!

Prince Harry, Meghan Markle, Prince William and Kate Middleton reunited at Buckingham Palace on Tuesday at a reception to honor Prince Charles, which was hosted by Queen Elizabeth. The event, in celebration of the 50th anniversary of the Prince of Wales' investiture, marked the group's first time together since attending Christmas Day services in Sandringham.

Meghan, who's expecting her first child next month, stunned in a white Amanda Wakeley coat and a floral, metallic brocade, knee-length dress. Kate, meanwhile, opted for a pastel-colored midi dress with ruffled sleeves and button details.

The group's outing comes amid rumors of a rift between Meghan and Kate. Royal expert Katie Nicholl previously told ET that the duchesses just needed time for their relationship to blossom.

"When Harry met Meghan, [as] the relationship was progressing, he was really keen to get Kate's stamp of approval. He wanted them to be close as sisters-in-law," she explained. "I think they're still in an early stage of their relationship. They're still really getting to know each other and there are many, many more years to come. A firm friendship could well blossom; I don't think it's out of the question."

"I think people forget these are still [the] early days and I think it's a matter of all of them trying to find their feet as a foursome," Nicholl continued. "For so long we had the royal trio -- Prince Harry, Prince William and Kate. Now, of course, we've got Meghan."
