Pop star Robbie Williams has invited his fans into the labour room by posting videos and photos showing his wife Ayda Field giving birth to their baby son.
He can be seen singing and dancing while Ms Field is in labour in the clips.
At times the 35-year-old actress joined in the fun enthusiastically, but she seemed less impressed when the singer boogied inches from her face as she was having a contraction.
The series of tweets began with a picture of Ms Field on a hospital bed in stilettos.
Take that: Robbie shows off some off his moves
Williams, 40, told fans: "When Ayda goes into labour she comes correct."
The former Take That singer then posted a clip of her twerking to Iggy Azalea's hit Fancy and himself dancing to his own hit Candy.
Another video showed him serenading his wife with the song Let It Go from the hit children's movie Frozen.
Williams said he has "never been more in love and never been more proud of my wife" as he announced the birth of his son.
He added: "It's been a very emotional, amazing few hours and we're really happy and honoured that you experienced the journey with us." The couple, who have a daughter Theodora, said they were still considering names for the new baby. Williams revealed he weighed 8lbs 1oz - before being corrected by his wife who said he was 8lbs 2oz.
"Every ounce counts, trust me," she said.
Williams married Ms Field in the grounds of his Beverly Hills mansion in August 2010, and Theodora was born two years later.
