This little boy doesn't really understand what a gender reveal cake means

Gender reveal cakes have always been a big thing, especially across the pond. 

They are a great way to reveal if you are having a boy or a girl and, of course, because you also get to eat the cake!

However, one little boy didn't really understand the concept of the reveal, but it makes for a very hilarious video!

Back in 2014, expectant mum Sandra and her husband, Joseph Sifuentes, decided to tell their kids if they were getting a baby brother or sister with the help of a giant white cake.

However, it wasn't just any cake; inside it had either pink or blue filling depending on whether the baby was going to be a boy or a girl.

Cutting into the cake, the oldest child Lainey can barely look. 

However, she gets what she wishes for: a baby sister. 

Adrian, on the other hand, really wanted a boy. 

"A girl," he shouts when he sees the filling. This is quickly followed by an "aw" when he realises it means he's getting a sister.  

However, that is not the funniest part; the young boy then leans over and peeps into the sliced cake. 

Not really understanding the whole concept, he looks into the cake wondering where the baby is before telling his sister that her baby "is not coming out". 

Just watch the video, it's incredibly sweet!
