Niall Horan is celebrating his 19th birthday today, and while he’s tucking into birthday cake in his Irish hometown of Mullingar, his celeb friends have been tweeting birthday wishes.
Olly Murs tweeted: “HAPPY BIRTHDAY @NiallOfficial have a ledge birthday dued!! Wherever you are in the world!! ENJOY!!”
Harry Styles tweeted: “@NiallOfficial HAPPY BIRTHDAY MATE!! Hope you’re having a good one. Big love .x”
But the mystery comes in the form of a tweet from Alfredo Flores.
He tweeted: “London nights! Chillen wit the bros @justinbieber @zaynmalik and we just left @niallofficial the best bday voicemail! Happy Birthday bro!”
What could it be?
Maybe a ‘swaggy’ version of the classic ‘Happy Birthday’ song?
Ooh the mystery.
What do you think? Comments please!
