It’s a big day for the Duke of Cambridge as he celebrates 30 years of poise, compassion and being generally dashing.

You might expect Prince William to have a huge birthday bash. On the contrary, it is reported that he is celebrating this landmark birthday with only his wife, Kate Middleton, and close friends and family in a low-key event.

The royal dreamboat celebrates his birthday on June 21, which means he has inherited $15 million from his late mother Princess Diana‘s estate. Though he was supposed to be given the money on his 25th birthday, a modification in his mother’s will after her tragic death in August 1997 changed the circumstances.

It’s not to say William, who married Kate Middleton, 30, in April 2012, doesn’t work for a living: he earns roughly $60,000 a year (American) for his time in the Royal Air Force.

However, towards the end of this year, he will need to decide if he wants to continue with the RAF, or begin pursuing royal duties full time.

So today, Prince William, we wish you a happy and healthy 30th birthday!
