Robbie Williams' wife Ayda Field has given birth to a baby boy after the star live tweeted her labour for hours in videos from the delivery room.
Robbie announced the happy news in a final video message, saying he's 'never been more in love'.
As he sat next to his 35-year-old wife on her hospital bed, the singer told his audience:
"Erm, so, he's here. It's ten past three on what day? Monday? And we've been up way over 24 hours. I've never been more in love and I've never been more proud of my wife, she's been absolutely astonishing."
He added: "Er baby bud isn't having a name yet, we're still figuring it out. He's 8lb 1oz," to which Ayda says "two ounces babe, every ounce counts."
Robbie added: "And the universe just presented itself to us again and it's been a very emotional, amazing few hours, and we're really happy and honoured that you experienced the journey with us."
He then wrote on Twitter:
Throughout Monday evening, the former Take That singer uploaded several videos to Twitter, including him giving a rendition of Frozen's Let It Go as Ayda prepared to push.
More footage showed the singer dancing and singing as Ayda got settled in, before Robbie pretended to be asleep next to his tired wife.
The couple were clearly enjoying the experience as Robbie's videos show them larking around in the maternity ward, performing dance routines for each other and Ayda showing off ruby red stilettos with her feet up in hospital bed stirrups.
Five hours after Robbie posted the first photo and video from the hospital, he felt his fans might need an update on the well being of those in the delivery room.
"We've been here since 10 o'clock last night," he says looking straight into the camera. "I know you're really concerned and worried and thinking about what's going on. I need you to know that... I'm doing great."
But it looked like the couple wouldn't have too much more time to kill before their second baby was born, as at 3.08pm Robbie posted a video showing Ayda having her waters broken.
"Will it go over my gown?" asks a concerned Robbie, who is advised he may want to stand back.
That was followed by a video with Robbie attempting to distract Ayda from the pain of contractions by discussing his 'comfy' fashion choice.
The 40-year-old singer - who married Ayda in 2010 - already has two-year-old daughter, Theodora 'Teddy' Rose, with the actress.
