After 15 years with Today FM, broadcaster Mairead Ronan has decided to leave the station.
The mum-of-two said she had decided to "jog on" and try new things.
She admitted she was both scared and excited about leaving the station.
Ronan started out on Ray D'Arcy's popular show before working behind the scenes as a producer on Ian Dempsey's flagship programme.
Last night, Mairead said she had been "so lucky" to spend "an exceptional 12 exhausting years with the Ray D'Arcy Show and the pleasure of producing the brilliant Ian Dempsey Breakfast Show since 2014".
She added that her increasingly busy TV career had contributed to her decision.
Mairead currently fronts Ireland's Fittest Family on RTE and will return to BBC Northern Ireland's travel series Getaways later this year.
"I've decided to take a large leap and try new things," she said.
Last September, Mairead and her husband Louis Ronan welcomed their first daughter Eliza into the world.
There have been several big changes within Today FM radio buildings in the past few months.
In December, Anton Savage announced that he was standing down from the station.
At the time, he said: "My objectives for the show and the new management's objectives for the show diverged greatly.
"We disagreed on a move to set music quotas; we disagreed on significant changes to the playlist; we disagreed on topics for discussion; on format; on choice of contributors, and we disagreed on the choice of certain guests. It led to a situation where we have parted ways."
While Anton was a great loss, Today has acquired some impressive talent, including comedian Al Porter.
