Shannon Noll and wife Rochelle welcome their fourth child, a son

Australian singer Shannon Noll and his wife Rochelle have welcomed their fourth child.

The couple revealed to New Idea on Monday that their son, who’s name has yet to be revealed, was born on December 30, weighing in at 3.6kg.

The youngest Noll will have older siblings Cody, 17, Blake, 15, and Sienna, 11 to help look after him.  

Shannon and Rochelle, who celebrated their 14th wedding anniversary in May 2018, announced they were expecting their fourth child back in July. 

Previously, Shannon said being away from his wife during his stint on I’m A Celebrity was the reason for the conception of their baby. 

The Lift crooner and his wife were reunited after he spent 42 days filming the reality show at Kruger National Park in South Africa between from January to March 2018.

‘This all happened around Easter, which was only 10 or 15 days after I got back from the jungle,’ Shannon told New Idea in July last year.

He added: ‘I think the show is the reason we got pregnant!’

The birth of the newborn comes after Shannon was told he could no longer have children following a freak ute accident in 2010. 

Oh baby! News of Shannon and Rochelle’s baby joy comes after the singer said being away from his wife during his stint on I’m A Celebrity, was the reason for the conception of their baby 

In a previous interview with New Idea, he explained: ‘I left for London a few days [after the accident] and half way through rehearsals I was in agony.’

‘The first thing the doctor said was, ‘I hope you’re finished having kids’, so we didn’t think there was any chance,’ he added.

Shannon rose to fame in 2003 during the first season of Australian Idol, finishing in second place behind eventual winner Guy Sebastian.

In recent years, he has enjoyed a resurgence in popularity among millennials due to his status as an Internet meme.
