RTE Late Late Show viewers were left in 'awe' at Olympic gold medalist Kellie Harrington during Thursday night's St Patrick's Day special after the boxing champion burst into song.
Kellie appeared on the show, having been the grand marshal of this year's Dublin city parade, alongside Irish-American actor John C Reilly, the overseas guest of honour.
The pair won the nation's hearts as they spoke with host Ryan Tubridy about their plans for the rest of the year ahead.
The 32-year-old, who returned from Bulgaria last month with a gold medal in the lightweight division of the International Strandja tournament last month, said she would be heading back to work this weekend in St Vincent's hospital.
She said: "I'm still in there - I've had a bit of time off as I was getting ready to go to Bulgaria. But I'm back in there [St Vincent's Hospital] on Saturday and Sunday."
Kellie said she loves her job working as part of the cleaning staff at the psychiatric hospital and told how her gold medal doesn't define her.
"It doesn't define us, the medal. It's an Olympic gold medal - it's a nice thing to have, but I'm also a nice person - I think so, anyways."
Kellie blew viewers away as she showcased her vocal skills singing the famous Irish song Grace.
The poignant performance moved many in the audience to tears as the boxer belted out the tune encouraging the studio audience to sing with her.
Taking to Twitter, people praised Kellie, saying: "Just in total awe of how fabulous Kellie Harrington and John C. Reilly's singing was. A fantastic way to start the show!"
Another wrote: "@kellieharrington's face when John C Reilly sang @raglanroad or @Kellieharrington's version of Grace? I'm not saying I cried but someone definitely cried!".
