Wife Ayda Fields went into labour yesterday, and excited dad Robbie was on hand to provide some, erm, entertainment for his baby momma.
After singing to Ayda whilst she suffered through contractions, Robbie updated his Twitter account filling in fans on everything that was going on in the maternity ward.

He typed: "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," Robbie says in the short clip.
"Er baby bud isn't having a name yet, we're still figuring it out. He's 8lb1oz," to which Ayda says "two ounces babe, every ounce counts.(sic)"

Following the intense labour, he told fans: "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: "'No Moms Were Harmed' Thank you for sharing the journey with us, we have been blessed with a beautiful baby boy. RW x."
The couple have not yet revealed the name of their newborn son.
Ayda and Robbie are also parents to two-year-old daughter Theodora Rose.
