Prince Harry and his new girlfriend Florence Brudenell-Bruce are cousins.

But don’t panic – they’re eight times removed, a family tree reveals.

Prince Harry, 26, is reported to have been on “one or two” dates with the posh lingerie model, her friends have confirmed.

Brudenell-Bruce, 25, who wants to make it as an actress, is an old flame of Formula One racer Jenson Button.

She is also related to Prince Harry’s step-mum Camilla and his late mother, Diana Princess of Wales.

Prince Harry has apparently been driven to Florence’s £2.5million home in Notting Hill, West London, for some late night rendezvous, but they both have insisted to friends that they are not living out a romance – yet.

Harry is said to have ended his on-off relationship with South African heiress Chelsy Davy.

A pal of Brudenell-Bruce said: “They have met one or two times for dates, but it’s nothing serious. They’re just having a bit of fun. She’s very focused on her career. But who knows where it might go?”

Her dates with Prince Harry appear to have been common knowledge in royal circles.

Still, the pair is in good company. His gran, The Queen, is a third cousin of husband Prince Philip.
