Niall Horan has always been the cheekiest member of One Direction and he's now proved that by peeing in public.

The pop hunk reunited with band mate Louis Tomlinson on Friday night and they headed out in West Hollywood to party.

But it seems they might have drank a bit too much liquid, as Niall was photographed doing a wee against a lamppost on his way home and his fans have gone crazy, which isn't really surprising.

Keeping it together one fan wrote: "SEEING NIALL PEEING IN PUBLIC IS SO CUTE AND I DON't EVEN KNOW WHY JAAKSLJLSDJDNDJ" Bizarre.

Others seemed to find it endearing, with one posting: "I keep thinking about how much Niall is cute even when he's peeing and I can't stop"

Another added: "I love how the only drama we get from Niall is him peeing in public. Omg you Niall are so cute haha! #OhNoNiall"

One pointed out it wasn't the first time: "The best picture of Niall peeing will always be the one where he's in the soccer uniform and you see his cute little butt"

Some did acknowledge if he wasn't Niall, it wouldn't be as adorable: "when people pees on the streets, me: so disgusting. When niall pees in public, me: aww,he looks cute even while peeing. Lol"

Though not everyone was impressed: "Assuming niall was peeing on a wall/concrete, and not grass, let's all agree that spitting or peeing in public/streets is disgusting."

The Irish stud hit 1 Oak nightclub in West Hollywood with Louis during his visit Stateside and the new dad seemed pretty happy to be reunited with his fellow 1D member and took to Instagram to post a snap of the pair hanging out on Saturday.

The star - who has been living in Los Angeles since the birth of his son Freddie in January - was joined by his sister Lottie for the night out.

Niall is clearly the squeaky clean member of the group, despite the fact he could have been slapped with a fine if he was caught peeing in public by the police, as well as possible community service.

But with Louis' baby surprise, Harry Styles allegedly cheating on Kendall Jenner and Liam Payne hooking up with married Cheryl after her recent split, Niall whizzing in the street is hardly the biggest One Direction scandal.
