John Krasinski & Emily Blunt: New Couple!

The Office star John Krasinski and The Devil Wears Prada actress Emily Blunt are dating, reports Star.

On Nov. 9, the couple stayed at San Ysidro Ranch in Santa Barbara, Calif. “They ordered room service, took long walks and spent every second together,” says an insider. “John really cares for Emily – he totally fawns over her. And she’s loving the attention. She’s a down-to-earth girl, but it’s nice to be treated so well.”

John, 29, currently plays smirking paper salesman Jim Halpert on the hit NBC comedy. Emily, 25, was the icy assistant to fashion magazine editor Miranda Priestly (Meryl Streep) in The Devil Wears Prada.

Blunt split with Canadian crooner Michael Bublé four months ago. Krasinski was last linked to his Office costar Rashida Jones.
