Hurtin Me Stefflon Don feat. French Montana Download 'Hurtin Me' on iTunes
They're one of our favourite boy bands, and we've pinpointed 14 instances that just made us fall in love with JJ, George, Josh and Jaymi that little bit more...
He may have needed some extra padding, but we give him an A* for effort - it's just like the original! Picture: Twitter/Paper Magazine
George posted this adorable festive throwback snap - we definitely wouldn't mind helping to decorate this tree! Picture: Twitter
Is it weird that we still find him attractive despite the dodgy wig? Is there any hairdo this boy can't pull off?! Picture: Instagram
Those ARMS. Those PECS. We can not cope. Picture: Twitter
Yeah, we know it's not as good as the real thing but the actual Union J are far less portable.
We LOVE that this pair have been together long before Jaymi joined the band, and are engaged and planning their wedding. They are definitely our OTP. Picture: Twitter
Proof that these boys were blooming GORGEOUS from day one. Look at that little angel face! Picture: Twitter
Because what else would you spend your downtime doing when you're not running away from hoards of screaming girls? Picture: Twitter
Derek is George's nerdy alter ego complete with a centre parting and glasses. We think he should become the fifth member of the band! Picture: Twitter
The boys proved their love for each other with matching coordinate tattoos in different places on their arms - that's true friendship! Picture: Instagram
Proof that cute animals and babies make even the hottest boys a MILLION times hotter. The entire #JCat fandom melted when Princey was born, and he's definitely the cutest member of Union J. Picture: Twitter
We loved their lip sync to this booty loving anthem - and the dance moves were pretty choice too!
Seriously guys, is there something you're not telling us…?! Picture: Twitter
They ACTUALLY flew in like four perfectly coiffed little angels. Picture: PA
