Irish X Factor hopeful Brendan Murray has said he is "happy" with the performance he gave during the first live show despite Simon Cowell saying the intro was "boring".

The 21-year-old former Hometown star, who represented Ireland at this year's Eurovision Song Contest, impressed the judges with a stripped back version of Ariana Grande's catchy pop tune, Break Free on Saturday night.

The Galway native received positive feedback from his mentor Louis Tomlinson, and  judges Ayda Field and Robbie Williams, while Simon Cowell was booed by the audience for saying he thought the first minute of the song was "boring".

Former Take That star Robbie Williams said he "smashed it", while his wife Ayda said Murray's performance was "unique and enchanting".

Ex One Direction star Louis Tomlinson said his act "really really delivered" and he "did himself proud".

After Cowell criticised Murray’s cover for being "boring", Tomlinson shouted out, "oh, shut up, Simon!". When the 59-year-old head judge tried to comment again later, he was swiftly told to "pipe down" .

The Galway native took to Twitter shortly after his performance to thank fans for their support and to say he was "happy" with how everything went.

Tonight, the first results show reveals which of the acts impressed the judges the most.
