Ryan Tubridy and his partner Dr Clare Kambamettu tied the knot in an intimate ceremony in the West of Ireland at the weekend.
The couple married in a ceremony attended by "their close friends and family" on Sunday afternoon, it was announced in a statement.
The radio and TV presenter confirmed his engagement to Kambamettu in June on his Virgin Media UK radio programme, which is broadcast on Q102 in Ireland.
The broadcaster said at the time: "It is a very beautiful feeling. We were surrounded by gorgeous people who we didn't know, strangers in the hotel, and people who were working around the place. I got a beautiful ring organised, and the weather was gorgeous.
"It was just an accumulation of a lot of lovely things happening, and I just decided 'Now is the time, here we go'."
He added: "It's a very exciting time to be alive, I'm a very, very lucky man. I think it's one of those beautiful moments where the world feels lighter and there's a whole new adventure ahead.
"Lucky man, beautiful day, and the future is bright."
Tubridy and Kambamettu, a clinical psychologist and a former Rose of Tralee, are believed to have begun dating after she appeared as a guest on his former RTÉ Radio 1 One show.
