After he provided a live commentary throughout his wife's labour, the 40-year-old singer posted another video message entitled "Charlton Valentine Williams has left the building... and Daddy is doing just fine", on his Twitter page on Wednesday.
The short clip shows Ayda, 35, pushing Robbie in a wheelchair down a hospital corridor. We then see Robbie sticking his arm out as he directs his wife round the corner before we finally get a glimpse of baby Charlton.

Robbie confirmed his son's arrival with a video filmed from his wife's hospital bed on Tuesday morning.
"Erm, so, he's here," he said in his message. "It's ten past three on what day? Monday? And we've been up way over 24 hours," Robbie says. "I've never been more in love and I've never been more proud of my wife, she's been absolutely astonishing."
Robbie added, "Er baby bud isn't having a name yet, we're still figuring it out. He's 8lb1oz." (Ayda quickly replied, "two ounces babe, every ounce counts.")
Charlton Valentine is Robbie's second child with Ayda. The couple welcomed their daughter Theodora, known as Teddy, in 2012.
