The first time I heard the term "Baby Mama" was probably on either Maury or Jerry Springer (don't laugh... you hear a lot of things as you're flipping over to PBS). It and its male equivalent, "Baby Daddy," essentially describes a person with whom you've had a child, but no other relationship currently exists. It used to be street slang, but in a movie world where pregnancy of all types seems to be the hot, go-to topic (Juno, Knocked Up), the whole "baby mama" thing was sure to come up at some point. I just never thought it would come from Tina Fey and Amy Poehler.
In Baby Mama, which opens the Tribeca Film Festival tonight and arrives nationwide on April 25, Fey plays Kate Holbrook, a successful vice president of a Whole Foods-esque organic supermarket chain. She's got the great job and the stunning Philadelphia apartment, but at 37, she longs for something more. You guessed it: Kate wants kids, and doesn't want to wait until she gets married to have them. One little problem: her chances of actually having a child are one in a million ("I just don't like your uterus," is what Kate's fertility doctor, played by The Daily Show's John Hodgman, tells her).
