Prince Harry and Chelsy Davy were back doing what they do best this weekend: Hitting the town.

The lively couple, who have been seen sharing dinner together and on another date since she returned to the U.K early February, were out at a private members bar in Chelsea, London, until the early hours of Friday.

The couple split up last fall but are now seeing so much of each other again that insiders expect that Chelsy, 25, will be among the excited guests at the wedding of Prince William and Kate Middleton.

Later Friday, Harry, 26, joined William and Kate to sign a condolence book to pay respects to those who have lost their lives in the earthquake in New Zealand.

The prince and Chelsy went their separate ways Saturday, when Harry (who will be William’s best man) was with his cousin Zara Phillips at the England vs. France rugby game at Twickenham, London. (Zara had a special interest as her fiancé Mike Tindall was playing). Chelsy, meanwhile, headed north to Northumberland, England, to attend the wedding of royal pal Katie Percy. Also in attendance? Middleton’s sister Pippa, 27.
