There’s another baby on the way for Leelee Sobieski!

The actress, 30, is expecting her second child with husband Adam Kimmel, her rep confirms to PEOPLE.

Cradling her belly, Sobieski — who starred in Never Been Kissed, Eyes Wide Shut and the miniseries Joan of Arc — she revealed her happy news Wednesday evening at Christian Dior’s Cruise 2015 show in Brooklyn.

Debuting her bump in a cobalt creation from the line, the actress accessorized with a beaded bracelet spelling out “Mommy.”

She and Kimmel, a fashion designer whom she wed in August 2010, are already parents to 4-year-old daughter Louisanna Ray.

“I’m really seeing her curiosity come out now — she just looks so smart,” Sobieski told PEOPLE in 2010.

“If she laughs, I laugh. If I heard myself talking a year ago, I’d be like, ‘So boring!’ But that’s what happens. My baby is really fascinating to me.”
