Will found out on Thursday that Danny O'Donoghue from The Script had been chosen for the BBC1 talent show ahead of him.
He wrote on Twitter: "The voice came, the voice went.
"Going out tonight with an appetite for destruction ? guns and roses?"
He did what all disappointed men do and headed to his local.
And it must have been a good night.
He tweeted yesterday: "Major hangover. Just need to get these legs to work."
A source said: "Will went to The Joiners Arms, near his flat in Hackney, east London, with a few mates.
"He seemed in a remarkably good mood and was definitely enjoying a few drinks.
"Will chatted to fans and posed for pictures.
"Then after a fair few drinks, he hit the dancefloor as Rihanna blared out."
Just as well the DJ didn't play anything by The Script.
