Emily Blunt thinks marriage is an ''effing blast''.

The 'Devil Wears Prada' actress - who has been married to 32-year-old actor John Krasinski for three years - admits she is ''so happy'' being wed to her partner and is enjoying their time together.

She said: ''This is what I find difficult about my marriage: It's hard to sum up something that's so vital and means everything to you in a soundbite. Do you know what I mean? All I can say is that it's an effing blast. I'm just great and I'm so happy.''

The British star is keen to begin a family with her husband but she is just unsure about exactly when it will happen.

She added to Manhattan magazine: ''We want to have children, I just don't know when yet. I'm just not sure about the timing of all of that. We're both from big families, so I think it's something we want.''

Emily previously revealed she has become far less cynical since her wedding.

She said: ''I am much less cynical and more mushy about love now that I have found my perfect match because I know how wonderful it can be. I love being married - I definitely think the party starts after the wedding's over.

''John's very loving and stable, which suits me perfectly. I have never been someone who cultivates drama in my relationships. I'm also a sucker for funny and he's the funniest person I know.''
