One thing that most fans love to buy at concerts are t-shirts. So much so, they've even become a major trend in the fashion world.

But, one fan may have been left disappointed when she received a t-shirt from Justin's Purpose World Tour – and it had a very embarrassing typo:

Yep. The name of his OWN tour, Purpose, is spelt wrong. Instead, purose is typed on the back of the shirt. Ouch.

We doubt Justin actually knew about this, because we bet he'd have a major freaker.
