Prince Harry has ended his short romance with his latest sweetheart, underwear model Florence Brudenell-Bruce. The split comes just two months after the pair got together and sources have revealed that the prince just doesnt want to be 'tied down. Miss Brudenell-Bruce - who used to go out with Formula 1s Jenson Button - asked him to join her on holiday in Ibiza next month, but that will not now happen. The 25-year-old had won the approval of Royal aides and only two weeks ago they were described as a 'dream couple. They were reported to have got so serious that she had been introduced to Prince William and others close to Harry which was seen as a significant step. A source said she went 'down a storm in the Royal household. One of the reasons behind the split is thought to be his commitment to his work in the Blues and Royals in the Army Air Corps. 'Harry has a lot on his mind at the moment, a source told the Daily Mirror. 'He is concentrating on his Apache helicopter training. After that hes expecting to return to Afghanistan. 'Harry enjoyed spending time with friends over the summer, but he doesnt want to be tied town in a relationship when training, so he called time with Flee. DM
