Prince Harry and his ex-girlfriend Chelsy Davy remain friends after their on-again-off-again seven-year relationship ended in 2010... but is it really over? Prince Harry's two year romance with Cressida Bonas went belly up in 2014 and new rumors are swirling that Davy and her most recent beau, Charles Goode, have broken up and she and the prince have become quite chummy again. 

Inside sources say, the prince and Davy reunited at a memorial service for a mutual friend, Henry van Straubenzee, in December and they are still pretty chatty.

"They have mutual friends so they're always at the same events, but there was something about the meeting before Christmas," an insider told British magazine Grazia. "Since then it's been very flirty. Everyone in their circle jokes that Chelsy is Harry's Camilla because, like Camilla for his father, Chelsy is the one woman Harry could never get over."

Prince Charles and Camilla married in 2005 and almost 75 percent of Brits opposed the possibility that Camilla could one day be queen. A recent poll found that only 35 percent now oppose the same idea. After a decade, many fans of Princess Diana have come to accept that Camilla is the elder prince's "one true love," according to KPopStarz.

"Harry and Chelsy are talking nearly every day," the source told Grazia. "They have always had amazing chemistry, so it's no wonder they've been drawn back together."

Prince Harry and Davy separated in 2010 among whispers that Davy had no interest in royal living. "Chelsy doesn't enjoy life in the spotlight and the duties that come with dating the prince," the source told Grazia. "But her reluctance spurs him on. He loves a challenge and he's always seen her as the one that got away."
