Justin Bieber has casually laughed off some pretty hilarious new pictures that surfaced of him walking around Los Angeles with what appeared to be a suspect ‘wet patch’ on the front of his trousers.

In the images, the 22 year old Canadian superstar is seen exiting Earthbar in West Hollywood, walking around drinking green juice, checking his phone, casually strolling to his Range Rover… all with a rather prominent looking stain on the front of his $700 Vetements pants.

The pictures originally surfaced accompanied by some pretty scathing remarks via TMZ on Thursday (February 23rd), with many people initially comparing to an unforgettable scene in Adam Sandler’s nineties comedy movie Billy Madison.

Indeed, Bieber himself referenced the scene, captioning a re-tweet of the photos: “You ain't cool unless you pee your pants.”

He later offered a full explanation as to what happened to cause such a stain to get on his crotch area – and no, he didn’t look at Selena Gomez’s latest Instagram picture, if that's what you're thinking!

“Someone got me flowers and I was driving, made a turn, and the water spilled on my dick area… Didn't bother me if it made ya laugh nice!” he tweeted to his 91 million followers.

The singer, who is set to mark his 23rd birthday in the next couple of weeks, will resume his massive 161-date Purpose World Tour on March 6th at Perth in Australia.

The amusing pictures come just a few days after Bieber was named as the chief suspect in a fight that took place outside a Cleveland hotel in June last year, as Bieber attended the NBA finals in the city. He is also thought to have head-butted a man at a pre-Grammys party in Serafina restaurant in Los Angeles, after being snapped ‘playfighting’ with a friend.
