He shared passionate kisses with tattooed Jessica Donaldson, 26, while dating her in San Diego, US.
A source said Harry, 27, was “bowled over” by the brunette he met while on a flying course.
The dashing royal met Jessica two weeks ago at the Andaz Hotel in San Diego, California, where she works in the cocktail lounge.
Harry wound up locked in conversation with her in a corner of the VIP balcony of the hotel’s Ivy nightclub.
The pair then went on two dates in a week and were spotted sharing passionate kisses. This week, as romance blossomed, they exchanged flirty texts and calls. A source said last night: “She’s a really fun girl and he was clearly bowled over. Things developed from there.”
A pal of Jessica said: “She is full of energy, a bit wild and goes out a lot.
“She’s a cocktail waitress who serves the VIPs in the Ivy Club. She’s gorgeous and very good at her job. But she’s a funny and genuine girl. It’s easy to see why Harry fell for her.”
Their meeting came on Harry’s first weekend off from flying Apache attack helicopters at the remote El Centro base, 100 miles from San Diego.
Later that night, Jes is understood to have joined Harry and his air crew pals as they continued partying in a suite at the Andaz Hotel.
Next day, Jessica — who sports a large floral tattoo on her right side — met Harry for lunch at a beachside restaurant.
And last weekend he invited her to the famous Belly Up Tavern live music venue in nearby Solana Beach.
They were seen kissing on a VIP balcony as they drank tequila and beer and danced to live music. Around 1am they moved on to another bar.
A source said: “Loads of girls were trying to get Harry’s attention but he only had eyes for Jes. They were kissing and looked comfortable together.”
Army captain Harry is single after his relationship with Zimbabwean beauty Chelsy Davy, 26, ended. He will be at El Centro for another two weeks before continuing his training in Arizona.
