Prince Harry was linked to Chelsy Davy from 2005 to 2010
When he's dating the royal bachelor is attentiveness itself, whisking his lady off on romantic holidays and showering her with affection. Chelsy found this so intoxicating she stayed with him for six years on-off, despite the difficulties of them living on different continents.
His time with Cressida lasted less - two years - before the pressure of such a public romance began to take its toll on the society beauty.
So why does true love continue to elude the Queen's grandson? After all he's handsome and kind, with blood that's as blue as it gets. Moreover, his brother Prince William is happily settled with his wife Kate and a son that Harry clearly dotes on, telling everyone about his "chubby cheeks" and how he looks like a young Winston Churchill.
His cousins Zara Tindall, Peter Phillips, Princess Beatrice and Princess Eugenie are married or seem close to doing so, as do many of friends.
In the past year he has been at usher the wedding of Guy Pelly to American hotel heiress Lizzy Wilson. Then there was Thomas Thomas van Straubenzee's dazzling wedding to Melissa Percy, daughter of the Duke of Northumberland.
He, William and Kate are also thought to have received an invitation for the wedding of Charlie Gilkes in Italy.
Florence Brudenell-Bruce and Cressida Bonas are among the sweet, willowy girls who have caught his eye
In an interview with the Press Association, he said: "I don't think you can ever be urged to settle down. If you find the right person and everything feels right, then it takes time, especially for myself and my brother.
"You ain't ever going to find someone who's going to jump into the position that it would hold. Simple as that."
