Pregnant actress Marley Shelton showed off her baby bump in a chic cream dress with a gold embellished neckline, Vahan diamond bangles and strappy metallic heels at the premiere of Journey 2: The Mysterious Island on Feb. 2.

The Scream 4 actress and her husband, Beau Flynn, "couldn't be more excited" to welcome their second child this spring. They are currently parents to a 2-year-old daughter named West and we can't wait to find out what they name their newest child. (East? South?)
