The couple has been dating since November 2008.
Previously, Krasinski dated his “Office” co-star Rashida Jones, and Blunt was with singer Michael Buble for three years.
Krasinski is best known as the impish Jim Halpert on NBC’s “The Office.” In the fourth episode this season, he and Pam (Jenna Fischer) plan to get married. Krasinski also recently starred opposite Maya Rudolph on the big screen in “Away We Go.”
Blunt is most recognized by American audiences for her role as the diet-obsessed assistant in “The Devil Wears Prada.” She next stars alongside Benicio Del Toro and Anthony Hopkins in “The Wolfman,” which will be released in February.
