The new show airs from Monday February 13th
Comedian Al Porter is to take over the mic on Today FM's lunchtime show.
The announcement was made live on-air when he joined Dermot & Dave in studio.
The lunchtime seat became vacant when it was announced earlier this month Dermot & Dave were to host a new mid-morning show.
A comedian, presenter, singer, writer and actor, Porter was the youngest comedian ever to headline Dublin's Vicar Street in 2015.
He has just completed his 2016 comedy tour of Ireland 'Al Porter At Large: The Honeymoon Tour' - including sold out nights in Vicar Street and the Cork Opera House.
Commenting on the announcement, Porter said: "Today is a huge day for me! I grew up listening to radio and anytime I've been into Today FM, whether it's to talk to Ian, Matt or Dermot & Dave, who have been interviewing me since I was a kid, I've enjoyed each and every visit.
"I've come to realise that it's such a personal and intimate thing to have a relationship with listeners and over the past 12 months I think people have gotten to know me better.
"I brought people into my home at the end of last year and now I am looking forward to being in THEIR homes every day, not as a comedian but as a friend".
While Today FM CEO Keith McCormack said: "Here at Today FM we are delighted to welcome Al Porter - the broadcaster, comedian and entertainer to the team.
"Today FM is on an exciting journey, an evolution of the station, where we bring together new talent with established household names to offer our listener a great variety of music and talk."
Porter will present lunchtimes on Today FM from Monday February 13th.
