It looks like Marley Shelton is thinking pink! The Sugar & Spice and Grindhouse actress revealed to friends and family at her sister's San Francisco wedding this past weekend that she is expecting a baby girl with her producer husband, Beau Flynn. But Marley, who was a bridesmaid in the ceremony, is keeping everyone guessing when it comes to baby names. "She and Beau know what they're going to name her," an insider tells In Touch. "But they're not telling anyone — not even family!" Marley will appear next alongside Timothy Olyphant and Steve Zahn in this summer’s action-thriller, A Perfect Getaway.
