They may be on hiatus, but the boys of One Direction still take the time to remember each others' big days.

On Wednesday, February 1, Harry Styles' bandmates made sure to wish the singer-turned-actor a happy 23rd birthday, starting with Niall Horan, who tweeted, "Happy birthday, mate. Have a good day, see ya soon."

Liam Payne and Louis Tomlinson also jumped in to wish their fellow Direction a special day, the latter adorably signing off his tweet with "Much love, Payno."

And while Zayn Malik didn't wish his pal a happy birthday on social media, maybe he just sent a text.
