The pair, who have been quietly seeing each other for several weeks, were out in London's trendy Notting Hill district, where they visited the club Beach Blanket Babylon.
The occasion marks the first time Harry, 25, and Davy, 23, have been photographed together since they split early this year. Sources at the time always said they would remain friends and, while both have been linked with other partners since they parted in January (and briefly reunited two months later), they have gradually been spending more time together.
At Beach Blanket Babylon, they met drag queen Daniel Lismore, who messaged his Twitter page: "AHH Have been hanging with Prince Harry tonight! @ BBB Notting Hill. Still here in the office in 60s outfit. PARTY TIME! GET DOWN ON IT!"
Reasons to CelebrateAccording to owner Robert Newmark, "Harry and Chelsy actually had a very quiet dinner … next to an open fire, a very quiet and private part of the restaurant." Leaving around midnight, the couple then went to an old favorite, Whisky Mist in Mayfair, where they met up with Harry's cousins, Princesses Beatrice and Eugenie.
There was a double reason to celebrate Friday – Harry passed his basic helicopter piloting exams and will now relocate to another base for the next stage of his training. That base is nearer to London, where Davy, who celebrates her 24th birthday this week, is a junior lawyer.
Harry's office at St. James's Palace would not comment on his reunion with Davy, but confirms that he is progressing in his career. It released a statement that said: "Prince Harry is delighted to have successfully completed the basic helicopter flying course. He will now embark on the next stage at the Army Air Corps base at Middle Wallop, Hampshire."
