It's hard enough keeping a new baby's gender a secret but parents Anna and Joe Williams went a step further and kept their twin pregnancy a secret until the very last minute.
This couple from Michigan in the US only revealed that they were having twins when they had already had them!
In the video above you'll see Anna's mother holding on tight to one of the twins, not knowing that she was about to meet another granddaughter.
Mom Anna says the couple thought that this would be a great surprise, considering that the twins arrived around Christmas Day. Not even the babies' older brother and sister had a clue that their numbers would double...
For more details and surprise reactions watch the video above.
