Prince Harry to end 5-year relationship with Chelsy Davy?

It seems the strain of a long distance relationship is taking a toll on Prince Harry as he is reportedly close to ending his five-year relationship with Chelsy Davy.

The couple is still officially together but the Prince, who just turned 26, has been telling friends he is single again, according to sources.

"Harry is a realist," the Daily Express quoted a source as saying.

The 24-year-old tried to end the relationship in June after abandoning her plans to work as a lawyer in London and moving back to South Africa.

She is apparently frustrated by Harry's absence as he trains to become an army helicopter pilot.
