The next time we see them out together will be when Kate Middleton walks down the aisle to marry her Prince.
The royal couple were undertaking their last pre-wedding public engagement on Monday - visiting Darwin in Lancashire.
Kate and the second-in-line are in town to officially open the Darwen Aldridge Community Academy and launch the SkillForce Prince's Award.
The prize will honour teenagers who "show significant character or make major contribution to the community".
Later in the day there'll be a pop star reception waiting for the royal couple, who will be greeted by as many as 10,000 well-wishers at Witton Park.
There William will sign a deed to protect the park and perhaps even have a kick-around when he meets a group taking part in a football skills training programme involving Blackburn Rovers.
