Spoiler alert! Big changes are brewing for the Walkers during May sweeps. In an upcoming Brothers & Sisters episode, Julia will go into early labor, which results in "scary complications" for her unborn twins. Luckily, newlywed Sarah Jane Morris, who plays Tommy Walker's (Balthazar Getty) pregnant wife, received lots of helpful advice from real-life mother of three Sally Field during her labor scenes.

"She was right there coaching me through it, holding my hand and rubbing my back," says Morris, who recently celebrated her first wedding anniversary with Rooney drummer Ned Brower.

Since she's never given birth herself, the actress was grateful that Field, who plays her on-screen mother-in-law, decided to tell her "what contractions are like." "Sally Field is my hero!" raves Morris. Ours, too. - Reporting by Dana Meltzer Zepeda
