In the unexpected crossover you didn’t see coming today, it looks like Justin Bieber is rocking Kim Kardashian’s SKIMS.

Well not in real life, but on a giant billboard poster alongside a huge building along LA’s Sunset Strip.

Kardashian’s SKIMS line creates a selection of loungewear, shapewear and undergarments such as undies and has become most identifiable for its minimalist designs and neutral colourways.

The ‘Peaches’ singer also found himself on a super identifiable ad recently for Balenciaga, where he is seen donning an all-black high fashion kit.

However, thanks to the recent stitch-up, we’ve come to see a whole new ad where Bieber isn’t rocking a full Balenciaga outfit, he’s actually rocking a pair of SKIMS undies below.

As per PEOPLEa billboard crew had began pasting up the Balenciaga ad over the SKIMS one on Monday.

It’s not 100% clear why the billboard ad wasn’t completely finished, or whether this was totally intentional. But what is clear is that a bunch of people caught a glimpse of it.

Of course that meant that photos of the cooked advertisement began circulating social media, in particular Twitter, with one user tweeting, “IM SO SORRY FOR LAUGHING BUT THIS IS WAY TOO FUNNY.”
