They'd have no regrets...
After eating his words about the X Factor and "everything they stand for" and having a listen to What Makes You Beautiful, N-Dubz's Dappy has revealed he's had a change of heart and is now a One Directioner.
Good news for the boys then as Niall Horan is keen to work with him - or as Dappy might say, do A WELL SICK MASH UP INNIT.
"Recently, since I’ve listened to a few of Dappy’s new tunes, I’d love to work with him," Niall told Capital FM - watch the boys on the show here.
“His new song is massive," added Harry. Maybe not quite as massive as your tune choon there Hazza, it's been sitting at the top of the charts ever since its release last weekend and looks set to officially chart at the top spot.
What do you think a One Direction and Dappy collaboration would sound like?
The Wanted have already confirmed a duet with N-Dubz for their new album, and Nathan hinted that Tulisa might be featuring on her own on one of their new tracks too, while Fazer's off to the studio with Katy Perry!
N-Dubz get around.
