Prince Harry, who is three weeks into an advanced weapons training course in California, reportedly invited cocktail waitress Jessica Donaldson (pictured, left) to his hotel room after a late-night drinking session.
According to staff at the Marriott hotel in Solano Beach, near San Diego, the 26-year-old Donaldson wasn’t seen leaving until 10.30am the next day.
Donaldson, who lives with her boyfriend of three years, nightclub promoter Brandon Thomason, was positively identified by at least two independent sources.
The 27-year-old Prince Harry, who is third in line to the throne, met Donaldson when he visited the Ivy nightclub in San Diego, a two hour drive from his base on Friday, October 7.
Prince Harry, who was with a large group of army air corps colleagues, as well as his Scotland Yard security detail, bought two bottles and began chatting with Donaldson.
At the end of the night, a man who Donaldson believed was one of his bodyguards asked for her number and said the prince would like to meet her for brunch the next day.
Jessica and a friend met up with Prince Harry and his group for scrambled eggs and carried on drinking fruit cocktails at a Mexican bar for the rest of the day.
He then got a friend to text Jessica and invite her to a see a band at the Belly Up Tavern, also in Solano Beach, the weekend before last.
It is there that they were pictured laughing and chatting intimately, sharing what appeared to be a long kiss on the lips.
But Donaldson denies that they did so, insisting that it was a "bad camera angle" and she rejects claims by staff at the nearby Marriot Hotel that she visited Prince Harry at his room: "It must have been another girl. I am sure Harry has lots of girls."
But one source at the hotel says: "Harry and the brunette were kissing (in the lobby). They ended up going back to his room. In the morning he walked her to a blue car that arrived to pick her up."
However, Donaldson says: "I am not sleeping with Prince Harry and he has never been anything but a total gentleman to me. I am very upset that this has all blown up. I’m flattered he showed me attention, but that is all there is to it. I really like him, but I have a boyfriend and I just want this to all go away.’"
Her boyfriend Brandon Thomason, added: "When I first saw the pictures of Jes with Harry I talked to her and she assured me that nothing went on. She told me they didn’t kiss and I believe her."
Prince Harry is an Apache attack helicopter pilot with the Army Air Corps and is currently completing the final stage of his training in the US with a view to returning to Afghanistan next year. He will be based in California until early December.
His spokesman at St James’s Palace has declined to comment on the reports.
