Clarence House has refused to comment on reports that Prince Harry has split from his girlfriend.
The News of the World reported that Chelsy Davy had ended their three-year relationship after the prince missed her 22nd birthday party to go to the Rugby World Cup final in Paris.
Miss Davy, who was born in Zimbabwe, had also become sick of the prince's playboy lifestyle and lack of commitment to her, the newspaper said.
Quoting unnamed "friends" of Miss Davy, the News of the World said the relationship ended in a series of emotional telephone calls between Leeds, where she is a student, and the southern African country of Lesotho, where the prince is doing charity work.
One told the newspaper the couple had worked better together when they lived 6,000 miles apart.
A spokeswoman for Clarence House said they did not comment on the prince's private life.
