Robbie and Ayda left hospital with their little boy yesterday (29 October) and announced his name alongside a new tongue-in-cheek video.
In the clip, Ayda can be seen slowly pushing a wheelchair and, as she turns a corner, Robbie can be sat in it while holding Charlton!
Posting the video on Twitter, Take That star Robbie told his followers: "Charlton Valentine Williams has left the building...and Daddy is doing just fine. RW x."
It's no surprise that the couple have announced Charlton's name in this way, as they kept fans updated in a similar fashion throughout Ayda's labour.
US actress Ayda gave birth to their son on Monday and, in the lead up, Robbie had shared some fun pictures and videos online.
In one snap, Ayda was wearing a pair of sparkly red Louboutins while in her hospital bed, and in a video the pair could be seen dancing around the room!
Robbie and Ayda are already parents to two-year-old daughter Teddy. We bet she's excited to have a little brother to play with!
