What to Expect When You're Expecting

It's too late to pull out now.

Challenges of impending parenthood turn the lives of five couples upside down. Two celebrities are unprepared for the surprise demands of pregnancy; hormones wreak havoc on a baby-crazy author, while her husband tries not to be outdone by his father, who's expecting twins with his young trophy wife; a photographer's husband isn't sure about his wife's adoption plans; a one-time hook-up results in a surprise pregnancy for rival food-truck owners.
