Why you'll see Chris Hemsworth rocking nail polish for an entire month.

Australian actor, super dad and possessor of excellent abs, Chris Hemsworth has just put his name and hands forward in a bid to help end violence against children.

Posting an image of himself sporting a freshly painted fingernail to his Instagram account on Monday, the Thor actor told his 6.8 million followers, “I just signed up to the @YGAP @polishedman campaign!”

Launched in 2015 by international not-for-profit YGAP, the campaign requires male participants to paint one of their fingernails in a bid to raise awareness about how prevalent domestic and sexual violence is among children under the age of 18.

“One in five children fall victim to physical and/or sexual violence, before they turn 18,” the father of three‘s caption continued. “That’s one too many. For the month of October, I’ll be painting one nail to represent this statistic and raise awareness and funds to end violence against children.”

Other participants in the campaign have included 30 Rock’s Alec Baldwin, actor Gyton Grantley, Olympic gold medalist Michael Klim, AFL star Chris Judd, tennis great Mark Philippoussis, Bachelors Sam Wood and Tim Robards, comedian and The Project panellist Lehmo, and musician Vance Joy.

Since returning to live in Australia with wife Elsa Pataky, twin boys Sasha and Tristan, and daughter India, Hemsworth has been active in his charity work, taking time out of his filming schedule for the next Thor film to visit a children’s hospital in Queensland with his co-star, Tom Hiddleston.
