It was the number one thing that 5-year old Eileidh Paterson wanted to do... diagnosed with terminal cancer, she just wanted to "marry" her 6-year-old best friend, Harrison Grier.
Well, her parents made her dream come true, in an amazing ceremony, and reception, attended by 200 people in the UK.
It was a princess superhero bash, where the two little kids, who have been close since they were infants, promised to be "best friends forever".
