Prince William's teenage son Prince George is already nearly as tall as him! George stood at almost the same height as his 6'3" dad in a video taken from the family outing in Glasgow. At one point, Prince William admitted that, just like all parents, they "embarrass" their teen son Prince George. Welsh TV presenter Gethin Jones later asked George outside: "Would you like to see mum and dad on a tandem in the velodrome later?" The birthday tributes continued with a video released later in the day of the Prince rock climbing with his younger brother, Prince Louis.
