Baseball caps are just the start of it.

Continuing her press rounds for 'The Girl On The Train', Emily Blunt sat down with IRL friend Stephen Colbert last night for a delightfully refreshing chat that actually resembled a chinwag between two friends and not a scripted awkward media attempt at a viral moment.

The highlight came when Stephen brought up Blunt's native England and how she'll be living there for eight months while filming her Mary Poppins sequel and how her husband loves the country but it doesn't love him.

Blunt also indulged Stephen by giving him some acting tips that are truly inspired.
