"You never, ever expect that someone's going to do that to you," Ashton recently revealed on Australia's 2DayFM, which you can watch in the video above.

"You gotta laugh. We made fun of him a little bit," Luke admitted. "But I think he was kind of upset about it."

And we don't blame him, especially considering the extraordinary amount of privacy violations that have occurred with celebrity nudes recently.

Still, Ashton couldn't resist cracking one more joke about the incident, revealing: "You're young and you do stupid s--- sometimes, but I stood next to him at the urinal and I was all like, 'I've seen that one before!'".
