Prince William and Kate Middleton hosted Hollywood actors Brad Pitt and Angelina Jolie Pitt in their Kensington Palace home over the weekend. The acting couple were invited by the British royal couple to discuss the fight against the illegal wildlife trade. It was the first time the two couples had met and, according to sources, the group got on very well, Us Weekly reported.

At around 3:45 p.m., Jolie Pitt, 40, a U.N. special envoy, and Pitt, 51, headed straight to Kensington Palace for the informal meeting over tea. Both couples got on so well that the meeting lasted longer than planned. The Pitts even brought a gift for the royals' newborn Princess Charlotte, who was born May 2. The foursome had tea together at the private meeting.

“The Duke and Duchess of Cambridge met with Brad Pitt and Angelina Jolie Pitt at Kensington Palace on Friday afternoon. They discussed their shared interest in combatting the illegal wildlife trade,” a Kensington Palace representative said. Another insider said William and Kate were “really excited” about welcoming their guests, and even waited outside their palatial home, Apartment 1A, to greet the Pitts. The source claimed that even Prince George -- who will be 2 years old in July, was present at the meeting, along with his parents. The source added that the actor couple spent a few hours at the palace. Prince William, Pitt, and Jolie all attended the 2014 BAFTA [British Academy of Film and Television Arts] awards but didn't cross paths.

The Hollywood couple had flown to London ahead of Jolie Pitt’s meeting on Monday, when she was to have lunch at the Foreign and Commonwealth Office and discuss the end to war zone sexual violence. In October 2014, Queen Elizabeth II made Jolie Pitt an honorary Dame Commander at a private Buckingham Palace ceremony, which is the female equivalent of knighthood, for the humanitarian work to which she has dedicated much of her life. The actress received the honor for her extensive service to British foreign policy.
