Royals Prince Harry Plays Tour Guide to Longtime Friend from the U.K. on a Bike Ride in California Harry wore a "California" baseball cap in a nod to his new home By Stephanie Petit Stephanie Petit Stephanie Petit is a Royals Writer and Reporter at PEOPLE. People Editorial Guidelines Published on May 25, 2022 02:32 PM Share Tweet Pin Email Photo: MEGA Prince Harry and Meghan Markle are hosting a friend visiting from the U.K. The Duke of Sussex was spotted riding his bike around his California neighborhood of Montecito accompanied by longtime pal Charlie van Straubenzee on May 20. Harry, 37, was dressed casually for the outing in shorts, a jacket and a baseball cap with the California state symbol of a grizzly bear on it. Harry and Charlie met at Ludgrove Prep School and have remained close ever since. Charlie and his wife Daisy Jenks were guests at Meghan and Harry's royal wedding in May 2018, and the Duke and Duchess of Sussex then attended their nuptials in August of the same year — on Meghan's birthday. Charlie and his older brother, Thomas, are also pals with Prince William. Thomas is one of Princess Charlotte's five godparents. Both Prince Harry and Prince William have also been supportive of the charity set up in the name of the van Straubenzees' late brother, Henry, who died in a car accident in 2002.

Harry and Eugenie have had a close relationship since they were children. "Out of all the Queen's grandchildren, Harry and Eugenie have one of the most natural connections. Like Harry, Eugenie is loyal, honest, and great fun. The two had many nights out together in London," authors Omid Scobie and Carolyn Durand wrote in Finding Freedom: Harry and Meghan and the Making of a Modern Royal Family. "Harry had always confided in his cousin when it came to the women in his life," the Scobie and Durand wrote. "Not only did he trust her implicitly, but friends say that she gives great advice and has always been 'beyond wise' for her years." Prince Harry and Meghan Markle.
