Justin Bieber fans were left in hysterics over a billboard placement which went very wrong and appeared to show the star wearing a pair of tiny grey pants.
The 27-year-old superstar accidentally became a model for Kim Kardashian's lingerie and shapewear brand, due to an awkward mashup of two ads on the billboard.
The Baby hitmaker originally appeared on an advert for Balenciaga, on the side of Andaz hotel in West Hollywood, California.
On his top half, the singing icon was wearing a leather jacket and looked super cool, but the bottom half hilariously saw Bieber in a pair of pants and socks.

It was football star Alex Morgan's bottom half that Justin appeared to be rocking.
According to Today, workers were in the process of removing Kim's Skims ad to make way for the Balenciaga ad when the mashup occurred.
But the mishap appeared to bring joy to fans as they took to Twitter to discuss the billboard drama.
" Justin Bieber for Skims Balenciaga is the happy accident you could only wish for on a Monday drive home," one person wrote.
A second shared: "Ok but why is this accidental balenciaga/skims billboard mashup actually the best ad campaign either has ever done?"
"IM SO SORRY FOR LAUGHING BUT THIS IS WAY TOO FUNNY," a third commented.
Meanwhile, 40-year-old Kim is reportedly thinking twice about divorcing her estranged husband, Kanye West.

An insider close to the Kardashian-West family has told that there is a chance that the reality star and rapper could rekindle their romance.
According to TMZ, the Yeezy fashion designer and SKIMS brand owner are "working on rebuilding the foundation of their relationship" as they continue to spend time together.
It's reported Kanye wants to get back together with his ex-wife Kim after her Donda wedding dress appearance.
The mum-of-four made an appearance at Kanye's album listening party while wearing a Balenciaga Couture wedding gown.

Kim and Kanye recreated their 2014 wedding nuptials on stage, and when the listening party was over, it was claimed they even left hand in hand.
According to a source, the Stronger rapper "sees the two together".
“Kanye wants to get back with Kim," the insider told Us Weekly.
"He sees the two of them together and wants to make that a reality now. He has been trying to get back in her good graces again and it seems to be working."
