A spider? A lizard? Jennifer Lopez and Milo Ventimiglia gave great OMG face when they last tried to figure out if they were touching vomit or just a bowl of guacamole. Now it’s Beckinsale’s turn.

The Widow star jumped and shrieked when she laid her hands on a stack of glazed cinnamon buns, but nothing compared to Fallon when he bravely put his hands inside the box and let his mind run wild with thoughts of what could possibly be inside. Turns out it was just a bunch of Peeps.
