Emily Blunt only just announced her second pregnancy but she's already rocking that pregnancy glow. The British star was spotted filming "The Girl on the Train" in New York City's Central Park. She wore a chic powder blue coat covering up her baby bump. Blunt looked picture perfect while taking a break from filming, chatting with some of the crew and taking a load off. She paired her gorgeous coat with a pair of low-heeled booties and jeans, but the best accessory was easily her ear-to-ear grin.
