Video blogging couple Sam and Nia shared one of the most special times in their life with their followers and it provided a tear jerking moment.

Nia had told her husband she suspected she might be pregnant, so without her knowing, he snuck a sample of her urine from the toilet to take a pregnancy test. Much to his delight, the test was positive and he was elated to get to be the one to tell her the happy news.

The adorable baby
announcement
, which shows their young daughter and son participating as well, has gone viral.

Nia took a second test on her own at the end of the video to make sure she’s pregnant, and low and beyond it was positive again.

Sam and Nia are high school sweethearts who live in Texas and often document their daily lives on YouTube. They seem thrilled about how much traction the video is getting on their Twitter, Facebook and Instagram pages, and posted a cute photo on Instagram after the video went viral.

“Does anyone here not know we're having another baby?” they wrote. “Our announcement may be going viral.”
