PIC: Bobby van Jaarsveld and Jo Black join the '10 year challenge' and the internet wants answers!

Cape Town - Celebrities are jumping on the "10 year challenge" bandwagon, and we just love this one of Bobby van Jaarveld and Jo Black.

Even though Afrikaans singer Jo Black got his big break in 2016 with his debut track Skepe, the musician has been singing for well-over 16 years.

Bobby took to Instagram to share a photo of the pair taken 10 years ago, and fans are convinced there's a good story behind the photo.

In the photo taken in 2008, Bobby's blonde hair is much longer, and Jo sports a barely-there beard. What a difference a decade can make! 

For now, both are keeping their lips sealed on the origin story!
