One Direction's Niall Horan enjoys boys' night out with Justin Bieber and Cody Simpson... just before being pictured next to 'suspicious looking glass pipe'
Niall Horan, Justin Bieber and Cody Simpson sparked concern from fans when they were spotted sitting alongside a suspicious-looking glass pipe over the weekend.
But in the run-up to the Snapchat video going viral, the boys were in great spirits as they got their big night out started in Los Angeles on Sunday.
The pop sensations caused a stir when they arrived at the Sunset Marquis alongside a group of guy friends, pulling a series of silly faces and larking around outside the hotel.

The One Direction singer was happy to pose for pictures with excited fans, with Bieber - clad in a green anorak and trucker cap - happily doing the honours.
While Niall has recently been linked to LA socialite Raquelle Stevens, Cody and Justin are thought to be single since splitting from Gigi Hadid and Selena Gomez respectively.

Cody, 18, has been making the most of his singledom since calling off his long-term romance with model of the moment Gigi.
The Australian singer was also recently spotted hanging out with his pals Miley Cyrus and snowboarder Shaun White at Nobu in Malibu.
The new images of the three boys' night out come just after Niall, Justin and Cody were seen sitting next to what appears to be a suspicious looking glass pipe in a photo, clearly taken the same evening.

There is nothing to suggest any of the boys have been taking drugs

MailOnline has contacted a spokesperson for Niall Horan, Justin Bieber and Cody Simpson for comment.
Justin and Cody have been close friends for some time and neither have made a secret out of the fact that they have smoked cannabis in the past.

In January 2014, sources close to Bieber claimed the young star was spending as much as £5,000 a week on marijuana.
Back in January, TMZ reported that Cody posted a picture of a packet of suspicious looking cigarettes, before deleting the snap.
Meanwhile, Bieber and Niall have been firm friends as far back as 2012 when the pair shared a picture of themselves cooking noodles at 2am.

At the time Justin tweeted a photo of the scene, adding in the caption: 'At my house cookin some noodles with @NiallOfficial.'
They met briefly in 2010 when television presenter Konnie Huq introduced the pair during a segment for Xtra Factor and they have since been pictured on a fan's Instagram account.
Niall is currently on tour with One Direction in the USA and the clip has emerged after he was pictured leaving Nobu in Malibu, with a mystery blonde by his side last week.
The singer was enjoying a rare night off from the band’s hectic tour which is now seeing them make their way across North America.

The boys will continue to tour around North America until September 12 when they end at Massachusetts' Foxborough Stadium.
Meanwhile, Justin made headlines when he appeared on the cover of Interview Magazine , where he talked about his new album - which he is currently working on with Skrillex and Diplo - as well as his love life.
Justin is currently single and focusing his attention on his family, he told Martha Stewart, who was conducting the interview.
He said: '[I have] no girlfriend at the moment, no. I'm single.'

?[I?m] excited, I?m happy to get it out there,? the mom-to-be, who?s expecting their first child in December, says before the big announcement.
?I honestly don?t care [if it?s a boy or girl] as long as it looks like her side of the family,? adds Aaron, an NBC news correspondent.
