The group's followers may well break Twitter with their outpouring of love on the singer's special day
Happy Birthday Louis Tomlinson!
The One Direction heartthrob has turned 23, and everyone's wondering where the years have gone - it seems like only yesterday he was a baby-faced teen auditioning for The X Factor.
Four years later, he's in one of the biggest bands IN THE WORLD and he's becoming a man.
1D fans have shown a lot of love for him on Twitter as he celebrates his special day, from custom cards to heartfelt messages.
Comedian James Corden joined in, joking: "Happy Birthday big d**k x"
