Vlogging couple Sam and Nia uploaded a new video that once again went viral after their famous lip syncing video of the song "Love is an Open Door" from Disney's "Frozen."

Sam had an inkling that his wife was pregnant since she missed her period for two weeks. Usually, when a woman is pregnant, she does the pregnancy test by herself, but Sam decided to turn the tables and sneak into the toilet to steal some urine for the pregnancy test. (Nia doesn't flush the toilet when she pees during the night so she doesn't wake up their other children.)

To his surprise, Nia was indeed pregnant. In the video, you could see his teary-eyed reaction upon knowing that his wife is pregnant with their third child. Now, it was Nia's turn to be surprised.

Sam went downstairs to his wife and children who were having breakfast. When Nia saw a positive pregnancy test, she thought it was just a prank. But when she realized it was from her urine, her reaction - as well as the kids' reactions - were priceless!

To make sure that the result wasn't incorrect because it was diluted with water, Nia did a second test at the end of the video. It was confirmed that she was indeed pregnant!

The video has now over one million views. The couple's YouTube channel has 175,000+ subscribers.
