Dear Beliebers, in case you were wondering about the size of Justin Bieber's nether regions, his trainer's got you covered. Let it be known: That's a sentence we never thought we'd have to write.

Justin's recent Calvin Klein ad is, naturally, being talked about ad nauseam -- from the head turning that came with its initial release to the scandal over whether or not Justin was heavily photoshopped, we're pretty sure that even if you live in a cave without Internet access you've probably seen the photos in some way shape or form. (Cave drawings will always be a thing.)

After a website posted what are allegedly Justin's photos pre-photoshop, people were, generally, less impressed. But now Justin's trainer, Patrick Nilsson, is coming to Justin's defense, saying to Access Hollywood, "I can definitely confirm that he is a well-endowed guy. I sound weird saying that, but yes."

So, there you have it, Beliebers. An inside source has confirmed that Justin has plenty to work with, so you can all rest easy.
