The third in line to the British throne reportedly started dating underwear model Florence Brudenell-Bruce - a former girlfriend of Formula 1 ace Jenson Button - after making it clear his on/off relationship with former love Chelsy Davy is over. A source told The Sun newspaper: "It`s very early days but Harry and Florence are an item. "She is a lot of fun, blonde and very good-looking. Harry really likes her." The couple have been meeting up at the £2.5 million home of Florence - who is a descendant of the seventh Earl of Cardigan - in Notting Hill, West London. While St James`s Palace refuses to comment on Harry`s personal life, Florence would only say: "There`s not much to say." The model - who has fronted campaigns for Adidas and British high street store John Lewis - and Harry have been casual friends for years with a number of mutual pals on the society party circuit. Florence could have some competition as Victoria`s Secret model Rosie Huntington Whiteley has revealed her obsession with the flame haired prince. She joked: "I`m waiting for my proposal. I keep writing. "I think he knows how obsessed I am. Well, he does now. He`s so handsome." However, Prince Harry, 26 - whose older brother Prince William married Duchess Catherine in April - has recently claimed he has no time for love as he is too busy with his work as an Apache helicopter pilot. Asked about rumours he had been dating Catherine`s sister Pippa Middleton, he replied: "Pippa? Ha! No, I am not seeing anyone at the moment. I`m 100 per cent single. "I`m working a lot at the moment, so dating and watching TV are the last things I have time for."
