A gender reveal party is guaranteed to offer at least one big surprise for the parents-to-be and their loved ones: the news of whether the new baby will be a little boy or a girl.
Whether the cake inside is blue or pink will reveal the baby's gender to those in attendance.
But for one mum-to-be, the big announcement was mixed with another very special moment, all planned by her partner.
Without giving too much, we'll just say that this clip is filled with all the emotions!
(And yes, among all the cheering, there is the big gender announcement – and everyone seems very happy with that news too.)
