“As you may or may not know, I have a foundation that focuses on ending the sexual exploitation of children and any help that you could give towards that would be an amazing present for me,” he continues.

He set up a Causes page, and tells fans he will match any money that’s donated to ending the sexual exploitation of children through his charity the Demi & Ashton Foundation (DNA). “I hope you can join me in that fight,” he says.

Ashton and his now-estranged wife Demi Moore created the DNA Foundation in 2010. After Moore was hospitalized in January, Kutcher returned from a trip to Brazil to get back to shooting his CBS comedy in late January.
