Tina Fey's baby hits the big screen this weekend. The "Saturday Night Live" alum and "30 Rock" mastermind stars in "Baby Mama," a comedy about a single businesswoman who hires a surrogate mom when she discovers she can't get pregnant. "Baby Mama" also stars current "SNL" cast member Amy Poehler as the eponymous lead. Fey and Poehler extend a long tradition of "SNL"-ers on the big screen. The two previously teamed up for 2004's "Mean Girls."
