The couple, who married in July last year, declared that although they want to wait before having children, it is definitely something that they would like to happen down the line.
"No we're definitely going to wait on that," Krasinski told E! Online at the premiere of Something Borrowed.
"I mean, hopefully we will at some point," he continued, explaining that they would only want a couple of children. "But we're waiting and definitely enjoying the honeymoon period if that's what we can call it."
When asked how he is enjoying married life, Krasinski added: "It's been a blast and I am so happy."
Blunt herself recently confirmed that she would love to have children with Krasinski in the future.
Both Blunt and Krasinski have cameo appearances in the upcoming Muppets movie, due to be released in the US on November 23, 2011 and in the UK on February 17, 2012.
