The 'Blue Lagoon' star revealed that she's ready for a son.
However, convincing hubby of six-years Chris Henchy is what the star is finding an uphill task.
"I want a boy! I'm going to have to convince him and he's a hard sell at this point," usmagazine.com quoted her, as saying.
She laughingly added: "Maybe he likes the even number!"
Shields is already mother to Rowan, 4, and Grier, 23 months.
The star is busy these days with her new primetime TV drama 'Lipstick Jungle' based on the best-selling novel of the same name by Candace Bushnell.
The plot is about three high-powered friends as they weather the ups and downs of lives lived at the top of their game.
