But the actress - who has probably the longest legs we've EVER seen - is reportedly nervous to take the role of a royal girlfriend.
A source told The Sun: “Harry is a huge fan of Gabriella - and she likes Harry a lot. But she is very wary of becoming another Kate Middleton.
“She is put off by the huge glare of the spotlight that surrounds everything Kate does.”
The privately-educated 23-year-old - full name Gabriella Zanna Vanessa Anstruther-Gough-Calthorpe - starred alongside Orlando Bloom in last year's film The Three Musketeers.
She's also had a role in BBC drama Doctor Who and is currently filming a remake of the 1976 horror movie Carrie.
And if Harry, 27, does nab Gabriella, he'll have done rather well for himself - she and her actress half-sister Isabella were once hailed the most eligible girls in Britain.
They were described by Tatler magazine as “quite possibly the glossiest, silkiest duo you’ll ever meet”.
Isabella, 32, is now off the market and engaged to Richard Branson's son Sam.
Gabriella admitted she was baffled by the label because she tries to keep out of the spotlight.
She said: "I don’t understand why I got anywhere near such a list.
"It’s the same with my sister Isabella - we both avoid the society thing.
"We never go to parties, we never hang out in the clubs associated with all that - we are incredibly private."
A string of glamorous girls have been linked to Harry since his split with long-term girlfriend Chelsy Davy, including model Florence Brudenell-Bruce, Saturdays singer Mollie King and even Pippa Middleton.
