The One Direction boys' love for each other runs deep. Although they haven't been seen together as often as before, they don't forget to offer each other support and send love whenever it is needed.
Louis Tomlinson, Niall Horan, and Liam Payne kept their birthday messages short and simple, all wishing Harry Styles' a great day ahead. Niall even hinted on a possible reunion with a "see ya soon" to Hazza. Check out their tweets below!
Former 1D bandmate Zayn Malik, however, hasn't tweeted a greeting for the birthday boy as of writing.
