Robbie Williams has revealed the name of his newborn son with wife Ayda Field.

The couple named their second child Charlton Valentine Williams.

The singer confirmed the news on Twitter, posting a short video of his wife pushing him down a hospital corridor in a wheelchair as he holds their newborn baby.

He jokingly tweeted: "Charlton Valentine Williams has left the building...and Daddy is doing just fine. RW x"

Williams and Field are already parents to daughter Theodora Rose, who they welcomed in September 2012.
