The video shows Ayda pushing a wheelchair down a hospital corridor. As she reaches a corner a hand reaches out from the chair pointing to the right and as Ayda turns she reveals Robbie sat in the chair cradling their baby.
Robbie titled the video "Charlton Valentine Williams has left the building... and Daddy is doing just fine. RW x"
This is the latest in a long line of videos shared by the proud dad over the past couple of days, as he live vlogged his wife's labour and the birth of his first son.
There's been no word from Robbie yet about how he and Ayda chose their son's name, but it's unlikely that the boy has been named after Charlton Athletic FC as Robbie is a proud Port Vale supporter (unless perhaps he's had a change of heart?).
A more likely bet is that Charlton Valentine has been named after a couple of vintage movie stars: Charlton Heston and Rudolph Valentino - as Robbie and Ayda have previously spoken about their love of traditional 'celebrity' baby names as opposed to modern 'celebrity' baby names.
Before the birth of their first child, daughter Theodora 'Teddy' Rose, in September 2012, Robbie said:
''I do have a sort of celebrity name but it's not Apple-esque. It's a very solid, old-school name.''
