While we were all expecting a Hello! magazine exclusive for big bucks, new mum Posh chose to show off her little lady herself instead, sharing the snap with her 1,477,576 Twitter followers with the message: 'Daddy's little girl!'
The pic shows new dad David snuggled up with little Harper, who looks like she's snoozing through her, very public, unveiling.
Later, David took to his Facebook page to upload another cute shot of Harper - this time with her proud mum.
What super-cute pictures! Still can't quite get our heads around the name though...
