Celebrities are weighing in on how often they shower. Here's what your favorite stars had to say about their hygiene preferences.

Shepard weighed in on the debate early, having hosted the episode that started it all. During the July podcast episode, he told his co-host Monica Padman that she "should not be getting rid of the natural oil on your skin with a bar of soap every day."

During an appearance on "The View" with husband Dax Shepard last week, Bell said she and Shepard wait for "the stink" before washing their children.

"I'm a big fan of waiting for the stink," she said. "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."

"Honestly, it's just bacteria; once you get bacteria you gotta be like, 'Get in the tub or the shower,'" Bell added. "So I don't hate what [Kunis and Kutcher] are doing. I wait for the stink."

Last week, Gyllenhaal told Vanity Fair that he finds it "less necessary, at times" to bathe, saying it's helpful for "skin maintenance."

"Good manners and bad breath get you nowhere," he said. "So I do that."

He added: "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."

Johnson said he is the "opposite of a 'not washing themselves' celeb", saying he himself takes three showers a day.

"Shower (cold) when I roll outta bed to get my day rollin'. Shower (warm) after my workout before work. Shower (hot) after I get home from work," he wrote in a tweet. "Face wash, body wash, exfoliate and I sing (off key) in the shower."

Cardi B tweeted her own response to the debate, saying, "Wassup with people saying they don't shower? It's giving itchy."

Though Moma, who plays an aquatic superhero Aquaman in the DC cinematic universe, wanted to exclude himself from being a part of the growing trend of celebrities voicing their opinions on shower habits, he did have a response to his "Sweet Girl" co-star Isabel Merced accusing him of not showering.

"I'm not starting any trends — I shower, trust me, I shower," he said, acknowledging the debate. "I'm Aquaman, I'm in the f---ing water, don't worry about it. I'm Hawaiian, we got saltwater, I'm good."

Like Dwayne Johnson, Crews told Access Hollywood earlier this week that he took three showers that day.

"I took one in the morning, after the workout, then I took one before I got here, then I took one in between acts," the "America's Got Talent" host said. "I love to shower because I spend so much time sweating."

He added: "If you've been sweating you don't need to shower but I spend all day sweating, running and working out and it ain't nice."

The actress and comedian left no one wondering where she stood in the debate, simply tweeting: "I bathe myself and my children every day."

Turner-Smith wanted to beat the public to the punch about her own opinion on bathing habits.

"before you lot even ask: in this house, we bathe," she tweeted, with a gif of Damon Wayans saying, "Homey don't play dat."
