Some of the biggest men in entertainment are flaunting their acting chops for a good reason. In partnership with Demi Moore and Ashton Kutcher's Real Men Don't Buy Girls campaign, Justin Timberlake, Drake and a string of other men have come together to film a series of comical spots to promote the movement's message against child sex slavery.

Kutcher took to

"We want to engage people, educate them, get them thinking and talking about it, in order to raise awareness and ultimately end child sex slavery," the actor wrote. "We came up with the concept of the 'Real Men Don't Buy Girls' campaign, which aims to engage people, specifically men, in the issue. To do so, we filmed short, funny videos about things 'Real Men' do, starring high-profile influential men and women."

In short, Kutcher explained that the message of the video campaign is that real men "do a lot of silly, even foolish things," but they don't buy children for sex. "That's not funny, and Real Men don't do it," he added.

In

However, instead of using a razor to remove his 5-o'clock shadow, the [article id="1659688"]newly single[/article] star cranks a chainsaw before a voiceover says: "Real men prefer a close shave."

Eva Longoria concludes the spot with a framed photo of Timberlake alongside fellow hall of fame "real men." Standing inside a log cabin, the actress offers another addition to the club: "Perez Hilton is a real man. Are you?" she asks.

Drake presents another strangely comical message

"Real men are distrustful of robots," says the voiceover.

Other "real men" participating in the campaign spots include Sean Penn, Bradley Cooper, Jamie Foxx and Jason Mraz, with similar video formats and the same signature closing tagline: "Real men don't buy girls."
