Ellie and Matt Greene have started a Facebook account for their daughter Marriah. Problem is, she is most definitely under 13. In fact, she's not even born. Yep, lil' Marriah is still cooking.
This fact has not affected her popularity though, as she already has 260 'friends', which surely makes her the most popular foetus in the world?
Ellie regularly updates Marriah's status as though it were her writing, spreading the word about her kicks and development.
The mum-to-be told America's KLTV that the page will be a nice thing for Marriah to see when she is older: 'We wanted to keep the page going, so she could go back and look at it.'
So what do you think of THAT Mark Zuckerberg?
And what do you think? Madness or a just the modern day equivalent of those twee baby books?
