He, of course, presented alongside Doireann Garrihy on RTÉ 2FM after his stint on Love Island to the delight of listeners.
He also showcased his presenting skills on Virgin Media’s rugby series, The Late Tackle with Muireann O’Connell back in 2020.
Sharing the news on social media, Greg enthused: “I’ve been wanting to tell you this for so long and now I finally can… I’m going to be a presenter on the @sixoclockshow !!!
“This is an absolute dream come true. I’ve done a couple years of presenting but I never thought I’d actually have a show. I’m so excited to start this journey and it’s made even better I’ll be beside the lovely @karenkostertv.”
He continued: “Also big shout out to @martinkingpresenter for such incredible work. You are an inspiration to me and I’ll never be able to fill your shoes but hopefully I’ll make it my own and do you proud on the show.
“Of course thanks so much to you all for your support as always, I can’t wait to start this new chapter!”
