Back in 2022, Roisin shared the announcement of her first pregnancy live on the radio, with the help of pal Greg.
Introducing her on the airwaves at the time, Greg said: 'Finally, we go to Roisin who is from The Wirral, and in the studio is sat in front of me.'
With Roisin then telling listeners: 'It's probably about time you all knew that I am having a baby.'
As Greg cheered at the news, he said: 'We realised we hadn't told any of the listeners yet and it was getting stupid', with newsreader Roisin adding: 'Actually, Greg you knew before my parents.
'It was just early morning work stuff, I had to tell you I'm pregnant.'
