It depends on how it's done, if it's tasteful and they're making sure that the boobs, the penis, and the vagina is covered it's okay, butts are fine. Plus it kind of matters what the meaning of the nudity is, like if it's some kind of message that's trying to be shown with nudity it's alright. I wouldn't call it gross because we were all born naked, we all get naked, it's natural. There was once a time when clothes didn't exist and people were naked, then they ate the forbidden fruit. With that biblical lesson aside, the human body is a a perfectly normal thing. Besides if celebrities are willing to get naked knowing that everyone they know will see it that's their business. Who are we to judge? I'm not a fan of nudity, though I do drool when I see some really hot celebrity women naked, I'm a guy, sue me. For those who don't know who these celebrities I used are they are Marilyn Monroe, Miley Cyrus (everyone knows that, DUH), and Justin Bieber, who's head was cut off but if you click in the image you can see it.

I only like it if it's hot guys naked!!!!!

...don't celebrities have anything better to do instead of getting naked in front of a camera... i'm sure there's better ways of becoming more popular...

its the humn body we all know what "private" parts look like

Agreed with KataraLover

Are they being tasteful or just plain vulgar. It all depends. Honestly I see noting wrong with the naked body female or male; it's how it's all about how it's used and exploited.
