'Happy Birthday, Zayn, You're My Hero': Zayn Malik Gets Inundated With 21st Birthday Wishes

We bet Zayn Malik is waking up to a thumping headache today if his 21st birthday celebrations were anything to go by on Saturday night.

The One Direction hunk kick-started his special day last night by inviting pals to his London pad for a proper shindig, which close friends of 1D band member Liam Payne took to Twitter to document.

We suspect Zayn won't be reading any of the birthday wishes flooding Twitter today until the late afternoon, but we've compiled some of the best for when he does eventually wake up.

"Massive happy birthday Zayn! Thank you so much for bring me all, have a nice day baby! I love so much♥ @zaynmalik"

"HAPPY BIRTHDAY TO THE MOST BEAUTIFUL AND PERFECT HUMAN BEING TO EVER WALK THE PLANET KNOWN AS ZAYN MALIK."

"Happy birthday zayn you're my hero happy 21st hope you have a great day!! Love you!! @zaynmalik #HappyBirthdayZayn."

However, not all the tweets were positive, with one fan urging the Little Things singer to post a message on Twitter considering today is a milestone birthday for the Bradford hunk.

"Zayn u haven't tweeted since december 19th don't u think it's time to tweet again it is your birthday for god sakes." (sic).
