Niall Horan celebrates 22nd birthday in Las Vegas with bikini clad clubbers (and Louis Tomlinson)
Theirs is a bromance to last through the ages, so it's only fitting that Louis Tomlinson would be the only 1D member on hand to celebrate Niall Horan's birthday.
The Mullingar native marked his 22nd birthday on Sunday and much like his 21st, he celebrated in Las Vegas.
This year however, the singer cranked up the celebrations a notch by jetting to Sin City with his bandmate and BFF Louis to party all night at XS Club - joined by bikini clad clubgoers and a handful of famous faces.
The pair, dubbed 'Nouis' by fans, were pictured enjoying vodka and champagne throughout the night to watch Diplo's performance and even shared a photo with Enrique Iglesias and Lil Jon, before eventually calling it a night at 5am and heading back to the Wynn Hotel.

Directioners nabbed video and photos of the boys at every opportunity, with Niall often waving to fans as he passed. Earlier in the day, the pair, pictured along with friends, enjoyed some low-key celebrations at their hotel's Encore Beach Club.
On Saturday night, he sang Taylor Swift's '22' to the crowd at Boston, before admitting "I don't know the words."

Niall was pictured wearing a protective boot on his right foot after revealing he fractured it last week - but has no idea how.
