Hawaiian babymoon for Blunt! Now expecting her first child, Emily Blunt hit the beach in Honolulu, Hawaii on Monday, Nov. 18 with her husband John Krasinski as well as their pal Bradley Cooper. Although the Looper actress, 30, hasn't said very much about her pregnancy, she happily bared her growing baby bump in a bikini as she hung out on the sand in a black, halter-style top and floral Seafolly bottoms.

Nearby, hubby of three years Krasinski, 33, enjoyed the warmth, sunshine and surf as he went shirtless -- with Cooper likewise revealing his buff torso. The two hunks are costars in the latest film project, thus far untitled, by director Cameron Crowe, which has been shooting in Hawaii. (Rachel McAdams also stars.) Blunt first debuted her bump last month while shooting Into the Woods in England.

Back in September, Us Weekly exclusively broke the news that the British actress was expecting. "We want to have children; I just don't know when yet," the Devil Wears Prada actress told Manhattan magazine last year "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."

Blunt and Office alum Krasinski wed in a star-studded ceremony in Italy back in 2010. A source told Us of the baby news: "They couldn't be more excited."
