Lingerie model Florence Brundell-Bruce, 25, has only recently started dating the third-in-line to the British throne but things are getting so serious she has already told pals Harry is `The One`. Florence - who is known as Flee to her pals - gushed to a former school friend: "It was a bit of fun but it`s getting serious. I think I might be in love." Another friend told The Sun newspaper: "Flee`s already said she loves being Harry`s girl and she has fallen for him fast." Florence - who previously dated Formula 1 racing driver Jensen Button - and the party-loving prince have many friends in common and also share a "wild side". The pal added: "She`s a party girl and Harry loves her wild side. Ibiza is one of her favourite holiday spots and she`s always in the Blue Marlin beach bar. She`s trying to get Harry to go." Harry, 26, reportedly wooed Florence with a cheeky pick up line based on polo practice, asking her "Fancy a spot of stick and balling with me?" The socialite replied with a flirty comment of her own, saying: "Well I do love redheads." The prince is said to have been further impressed when Florence wowed him with her party trick of drinking a shot while doing the splits. Harry has been single since recently splitting from Chelsy Davy his on/off girlfriend of seven years.
