Though there has been loads of speculation about the on-again, off-again relationship between famous royal bachelor Prince Harry, 26, and his lingerie model girlfriend, Florence Brudenell-Bruce, 25, the two are reportedly off-again, at least while Harry focues on his career in the British army, which now has him flying Apache helicopters.

"Harry has a lot on his mind at the moment," an insider told UK's Daily Mirror. "He is concentrating on his Apache helicopter training. After that, he's expecting a return to Afghanistan." Consequently, Flee, as his former girlfriend is nicknamed, is getting the cold shoulder from her beau since June. "Harry enjoyed spending time with friends over the summer," the source said. "But he doesn't want to be tied down in a relationship when training, so he called time on Flee."

This split could open the door to the popular rumors that Harry has eyes for his sister-in-law, Pippa Middleton, with whom he was seen schmoozing at the royal wedding of Prince William and Kate Middleton. Until his Apache training, which will take place through the winter in Arizona, is complete, we'll have to wait and see.
