The Prince of Wales, Duke of Cambridge, RAF rescue pilot and husband of Kate Middleton celebrates his birthday on the 2013 Summer Solstice.
Happy birthday to father-to-be Prince William!
It's good to be the future king any day, no doubt. Being married to Kate Middleton alone would make that the case. But soon he'll have an heir(ess)!
The couple has not found out the gender of their impending arrival - due next month - but he or she will assume a place in history from day one.
No pressure, kid.
As for his any big plans today? William is reportedly laying low lately, with any birthday commemorations likely to involve only family and close friends.
For good reason.
