Speaking on the Late Show with David Letterman on Monday, the X-Files star explained that she met him a few years ago at a red carpet event: “We all, mostly women, lined up. And when he gets to you, he takes your hand and makes eye contact.

“After he leaves and he moves on to the next person, he looks back at you and seals the deal.

“When I got home, I expected to have a message from him, and I didn’t. I bet women across America expect it too.”
