Prince George is currently third in line to the British throne, despite only being an adorable eight-year-old.
The young prince is behind his grandfather Prince Charles and his father Prince William, but before he is crowned himself he may have a few title changes to go through first.
Once his dad William is crowned King and his mum Kate is the Queen, George will be the next male heir to the throne meaning he will likely be awarded the title of Prince of Wales.
As this title must be bestowed upon the heir by the monarch, it's not a given it will happen - but it is to be expected that George will be granted it when the time comes.
As reported in The Mirror, George is likely to also get dukedom on his wedding day if and when he chooses to marry - meaning he may have two different titles before he becomes the Prince of Wales.
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."
