The couple posed for official portraits at Buckingham Palace earlier today, showing off Eugenie's massive pink sapphire ring.
"We met when I was 20 and Jack was 24 and fell in love," Eugenie told BBC's The One Show. "We have the same passions and drive for life." With Jack adding it was "love at first sight".
"I love Eugenie so much and we are just so happy and over the moon for what is to come," he said.
"Granny actually knew right at the beginning [of the engagement]. She was very happy as was my grandfather," added Eugenie.
Congratulations to the happy couple!
