Just when you think Hollywood couldn't get any dirtier, actor Jake Gyllenhaal comes out to admit he is not a fan of bathing.

He told Vanity Fair: "More and more I find bathing to be less necessary, at times. I do believe, because Elvis Costello is wonderful, that good manners and bad breath get you nowhere. So I do that. But I do also think that there's a whole world of not bathing that is also really helpful for skin maintenance, and we naturally clean ourselves."

That stinks.

But, of course, it isn't as if Jake is alone.

Apparently, Hollywood is full of people who believe the same thing.

Note that prior, power couple Ashton Kutcher and Mila Kunis also admitted to not bathing daily.

"I don't wash my body with soap every day," Mila said on his friend, Dax Shepard's "Armchair Expert" podcast.

Ashton added, "I wash my armpits and my crotch daily, and nothing else ever."

It applies to their children too.

Mila said, "When I had children, I also didn't wash them every day. I wasn't the parent that bathed my newborns—ever." 

Ashton added, "Here's the thing—if you can see the dirt on 'em, clean 'em. Otherwise, there's no point."

Dax might've encouraged the notion as he and wife, Kristen Bell, also do very much the same thing.

"We bathed our children every single night—prior to bed is like the routine," he said on "The View." "And then somehow, they just started going to sleep on their own without the routine, and by George, we had to start saying, 'Hey, when's the last time you bathed them?'"

Dax continued, "Sometimes five, six days goes along. I mean, they don't smell."

Kristen interjected, "Well, they do sometimes. I'm a big fan of waiting for the stink. Once you catch a whiff, that's biology's way of letting you know you need to clean it up. There's a red flag. Because honestly, it's just bacteria. And once you get the bacteria, you gotta be like, 'Get in the tub or the shower.' So I don't hate what they're doing. I wait for the stink."

Of course.
