This is why are male A-listers have been painting their nails

Zac Efron, Chris and Liam Hemsworth, and other male celebrities are participating in the annual Polished Man nail-painting campaign to combat child abuse.

The challenge is to paint a nail, post the photo and donate to the cause to help raise awareness for the one in five children worldwide who are victims of violence, according to the charity.

The third Hemsworth brother, Luke, who can currently been seen in Westworld, participated in the campaign last year. Surfer Kelly Slater also joined in, and they have tagged celebs such as Robert Downey, Jr., Jimmy Fallon, Hugh Jackman, Jeremy Renner, and Tom Hiddleston, so more manicured male celebs should be on the way soon.
