Emily Blunt admits her pal Jason Segel loves to get naked. The funnyman strips for a full-frontal scene in their upcoming romantic comedy "The Five-Year Engagement."

She told E! Online, "Jason was happy to get that thing out at all times. He seems to be very willing."

In the film (in theaters April 27), Emily and Jason play a couple who ride out an unusually long engagement. Judd Apatow produces, and Segel co-wrote the script.

The actor famously went nude in the 2008 film "Forgetting Sarah Marshall."
