If you actually look at them, the overwhelming majority of them are blatantly real. There are some games. But many of the celebs have confirmed they're real. The only ones denying it are the two Nickelodeon princesses Victoria Justice and Arianna Grande.
Yeah, do you really think I'm going to waste my time? I've seen plenty of nekkid women of all ages, shapes, and sizes in locker rooms over the years. Not gonna google them.
If the women are claiming them, then I guess they must be real. I've just learned not to be terribly trusting of viral pictures and videos on the net.
