A Boy or Girl for Ali Larter? Jimmy Fallon Uncovers the Truth (VIDEO)

Jimmy Fallon is too much of a gentleman to probe into Ali Larter's private affairs on 'Late Night' (weeknights, 12:37AM ET on NBC). When the question arose as to whether the actress was having a boy or a girl, he said he'd respect her privacy.

Or... he could just ply her with gender-specific gifts. The host offered blue and pink onesies -- but she could only pick one.

Larter complied. And which one did she choose? Check the video after the jump.
