Reports: Prince William and Former Girlfriend Kate Middleton Back Together

Prince William and former girlfriend Kate Middleton have resumed their relationship, British newspapers reported.

The young couple, who announced in April they had split, attended a party at an army barracks together earlier this month, newspapers claimed in their Sunday editions.

William, 25, has also invited Middleton to attend a memorial concert to his late mother, Princess Diana, to be held at London's Wembley Stadium next Sunday, the Mail on Sunday reported.

A spokeswoman for William's Clarence House office declined to comment on the reports.

"We don't discuss William's private life, it's a matter for him," she said, on customary condition of anonymity, in line with policy.

Britain's News of The World tabloid claimed the couple had been on a string of low key dates since their April split.

William, second in line to the British throne and a second lieutenant in the country's army, celebrated his 25th birthday Thursday and gained access to part of the inheritance left him by his mother.
