The tiny singer has already performed on a CD with his idols Westlife.
Now, the Sunday Mirror says he's landed a £1m deal with record giants EMI.
He records in his spare time when he's not doing his schoolwork.
Success isn't going to his head according to his dad, Alec:
"He's a down-to-earth lad who loves his bike and football."
But Pop Idol's 'Mr Nasty' Simon Cowell says: "Declan is unique. He knows what he wants and that's exceptional at his age."
