He may only be eight-years-old, but Prince George is already destined to be King.
The young royal is third-in-line to the throne behind his grandfather Prince Charles and dad Prince William.
But before he reaches the throne, he could be set for numerous title changes over this lifetime - and one dramatic change could see him bag a very grand title.
When his dad William is King and mum Kate is Queen, George would be the male heir to the throne.
And tradition is that a male in this position is awarded the title of Prince of Wales.
It is not a given that George will get the title, as it has to be bestowed upon the heir by the monarch.
However, it is more than likely that William will pass this title on to his eldest son.
George will also be probably given a dukedom on his wedding day if he chooses to marry, meaning he could have two different titles by that time.

So far, George has made rare public appearances with his parents and his siblings Princess Charlotte and Prince Louis.
On Saturday, he was taken to Twickenham to watch England's exciting Six Nations rugby clash with Wales.
Before kick-off, George accompanied his parents as they met representatives from the two rugby football unions and then joined them in stands for the big game.
And it seems the youngster delighted royal fans when he was caught on camera singing every single word of the national anthem God Save The Queen - alongside both William and Kate.
George could be seen looking up to both of his parents throughout the tune for reassurance as he sang the famous words.
And commenting on a video uploaded to YouTube of the moment, royal fans couldn't hide their delight at him singing them anthem, which pays tribute to his great-grandmother the Queen, whom he used to call "Gan Gan" when he was younger.
One royal commented on the clip saying: "Wills & Kate singing the national anthem was a treat.... and the shy Prince George singing for his Gan Gan."
And another wrote: "Wonderful outing with Mom and Dad! Prince George is such a credit to his parents and indeed the country. Loved the brightening on his face when singing God Save the Queen."
