In the heartwarming clip, which was originally recorded in March, the family can be seen gathered round a kitchen island.

Grace had already handed out personalized game cards to the group as the camera focused on Amanda.

She exclaims: 'I won! It says "we're having a baby." What the f**k? What does that even mean?'

The perplexed sibling calls others over to take a look at the playing card to verify what she was seeing - but she is still confused.

From off camera, Grace prompts: 'Who do you think...?'

And, at this point, the penny finally drops for Amanda who repeatedly screams in disbelief: 'Are you having a baby?'

She then takes a step back, steadies herself against the counter and gazes around the room with mouth agape.

Other relatives rush over to congratulate Grace but Amanda appears to still be rooted to the spot as she begins to cry.
