I think they're all notoriously blonde, but that's not as common with guys, I think. Off the top of my head--Ryan Gosling, Garrett Hedlund, Charlie Hunnam, Bradley James, Ryan Reynolds, Chris Pine, Dan Stevens, Justin Hartley, Matt Barr, Chris Evans, Calvin Harris, Domhnall Gleeson, Jamie Dornan, and not blonde, but has that great smile, Jake Gyllenhaal.
