We bet 5 Seconds of Summer fans aren't hoping for 'Amnesia' after this. Yesterday (Aug. 28), a nude picture of Calum Hood reportedly leaked online!

In the very, very, very NSFW photo, the singer allegedly rolled up his shirt and pulled down his pants, revealing what's, uh, inside. (You can check out a censored version of the photo right here.) While you can't see the person's face, Just Jared Jr. claims it's the singer and Calum himself seems to have 'fessed up based upon these tweets:

We applaud his honesty and ability to brush off the error. (Although next time, Calum, cover it up with some American Apparel underwear.)

The real question, of course, is who leaked the photo? It was technically a video sent via SnapChat and clearly screencapped, but beyond that, there's no other information.

Calum is just the latest in a long line of celebs who have nude photo scandals. Former Disney star Dylan Sprouse owned up to the naked pics of himself that leaked online, with 'Glee' actress Heather Morris and Demi Lovato reportedly suffering from unauthorized published images as well. However, some stars like Rihanna and Cody Simpson choose to flaunt their bodies proudly -- even when Instagram takes the photos down.
