Prince William celebrates birthday at work

June 21, 2011 12:49:45 AM PDT
Prince William is working as he turns 29 on Tuesday. The prince is a helicopter search-and-rescue pilot in the Royal Air Force.

He will be on duty at a base on an island off the coast of Wales and is expected to celebrate his birthday privately.

A low-key day may be just what the prince wants after his blow-out April wedding to Kate Middleton.

He is also getting ready for a trip to Canada and the U.S. next month. It will be his first official overseas trip as a married man.

William's grandfather, Prince Philip, recently celebrated his 90th birthday with a full day of official engagements.
