Jessica Hickey's father has been asking for grandchildren since her wedding night - and his response to learning she was pregnant is nothing short of delightful.

Hickey, an only child, made the big reveal while filming her dad opening a gift box with a pacifier and note inside. She posted the video of his reaction to Reddit saying:

" Told my dad he is going to be a grandpa I am his only child and my mother passed away 20 years ago. He has been asking us for grandchildren since our wedding night. I think he is happy. :)"

ABC News spoke to Jessica briefly who said her dad, in his 50s, has no idea of his new-found Internet fame.
