It comes after Dermot took to Instagram to announce the news as he gushed he was ‘enjoying the cuddles in a newborn bubble.’

‘Enjoying the cuddles in the newborn bubble… cats yet to be 100% convinced. Lots of love, Dermot & Dee x.’ 

Just a day before their son was born, Dermot revealed that he and Dee were celebrating their impending arrival with a ‘summer solstice’ theme baby shower.

Dermot and his wife Dee announced in February that they were expecting their first child together.

Taking to Instagram, they shared a fun picture of a message board decorated with a floral wreath which said ‘Koppang O’Leary productions’ would be welcoming a ‘new arrival coming soon’.

In the post Dermot penned: ‘We’re pleased to announce that we’re expecting a little Koppang O’Leary…’

Dee debuted her baby bump for the first time at the British Academy Film Awards 2020 Nominees’ Party in February.

Since then, the private couple have shared rare glimpses of Dee’s pregnancy during lockdown.

In April, the Norwegian producer and director showcased her growing baby bump as she revealed she had to do Dermot’s hair and make-up for the One World Together highlights show.

Dee joked: ‘No pressure… had to do @radioleary hair & make up for tonight’s @bbcone @glblctzn live show… (7.15pm).

It proved to be a star-studded occasion with guests including Holly Willoughby, James Corden and Bear Grylls.

In 2015 Dermot hinted that he was ready to start a family with wife Dee, telling Fabulous Magazine: ‘I definitely want kids, but I’ve got a very busy wife with a very busy life.

‘It’s not fair for me to say, ”I want kids now”. I do want kids with my wife, but I want them when we both think it’s the right thing to happen.’

Late last year ahead of his seventh wedding anniversary, Dermot also spoke about the secret to his happy relationship, telling Fabulous: ‘It’s a work in progress, isn’t it?

‘The key for me is giving each other space, not giving each other a hard time and actually having fun together. And we do.’
