The two actors took to their Instagrams after being nominated by Chris Hemsworth to take part in the Polished Man Challenge.
“Thanks for the nom, @chrishemsworth. Happy to paint one nail and be a @PolishedMan this month to say no to violence against children. 1 in 5 children are subject to physical and/or sexual violence before the age of 18 and that’s one too many,” Zac wrote along with his photo.
Liam added, “Thanks @chrishemsworth happy to also be a @polishedman and paint a nail this month to say NO to violence against children. 1 in 5 kids globally are subjected to physical or sexual violence before they turn 18.”
