The Duchess of Sussex and Prince Harry were headed to meet friends at a Sushi bar in Montecito

Prince Harry and Meghan Markle were spotted out in Montecito at the weekend, following the Duke of Sussex's flying visit to the UK for King Charles' coronation, but it's since been revealed the royal couple were joined by Hollywood royalty for their special date.

The Duke and Duchess headed to the swanky restaurant Sushi Bar in Santa Barbara restaurant to enjoy some food, but rather than dining solo, the couple were joined by some famous faces - including A-Listers Cameron Diaz and her musician husband, Benji Madden, which can be seen in the picture below. According to Page Six, the foursome were also joined by Gwyneth Paltrow and her husband, Brad Fulchuck as well as Bumble CEO Whitney Wolf Herd and Texas oil heir, Michael Herd.

Meghan looked stunning in a low-key glamourous look. The Duchess opted for neutral tones with a brown Heidi Merrick satin dress with a bucket bag from Cesta Collective. On her feet, Meghan wore some brown Hermes sliders. Harry, meanwhile, went for white trousers and a laidback, casual black T-Shirt.

Meghan and Harry, who share Prince Archie, 4, and Princess Lilibet, one, were no doubt thrilled to be back together following the Duke's visit to the UK the weekend prior for his father's coronation.

Prince Harry made a flying visit to London for the coronation which took place at Westminster Abbey on Saturday 6 May. The royal touched down at London's Heathrow on Friday evening and joined various members of his family at the ceremony.

In footage obtained from the coronation, Harry could be seen smiling at his cousin Zara as they walked into the Abbey, as well as greeting Princess Beatrice and her husband Edoardo Mapelli Mozzi, who placed a welcomed hand on the Duke's back.

Harry's appearance at the service was the first time he had reunited with his extended family since his explosive memoir , which was released in January, and the release of three-part documentary Harry & Meghan on Netflix.

Following the service, the father-of-two wasted no time heading back to Heathrow Airport to immediately board a British Airways flight back to California. HELLO! understands that Prince Harry made it back just in time for his son Prince Archie's fourth birthday celebrations, which took place on the same day as the coronation of King Charles and Queen Camilla.
