We've been watching his performace on Saturday night all day long - we just had to share it with you - again!
X Factor judge Dannii Minogue asked if he had a girlfriend and we reckon the whole country was wondering the same thing after he sang the John Lennon classic Imagine on the first live show...
So what do you think? Is Eoghan Quigg the cutest boy in the UK at the moment? Will he win X Factor? Tell us now!
The 15-year-old must be over the moon with his performance but his mum nearly missed out on coming to the show as she's pregnant. Instead of flying over from Northern Ireland, Mrs Quigg jumped on the ferry with Eoghan's dad Chris. It was certainly worth the trip as their son sang his heart out - bless!
