Congratulations to Leelee Sobieski! The actress is pregnant with her second child and debuted her growing baby bump at the Christian Dior Cruise Fashion Show in Brooklyn, New York yesterday, May 7.

Sobieski, who is already mom to 4-year-old Louisianna Ray with husband Adam Kimmel, stunned in a floor-length, two-piece navy blue gown. According to Just Jared, the actress, who was photographed cradling her sweet little baby bump, announced her pregnancy at the event.

Sobieski paired the midnight blue gown with a watermelon pink lip, black eyeliner on her top lids, matching navy shoes and several simple beaded bracelets on her wrist.  She wore her blonde locks swept off of her face in an updo, the perfect hairstyle for the three-quarter sleeved frock, which was buttoned together with two ornate brooches on the shoulder.
