Ali Larter's baby slip true!

Ali Larter revealed she is having a baby boy on Late Night with Jimmy Fallon.

Ali Larter's baby slip true!

Remember when we thought pregnant Ali Larter accidentally revealed the sex of her unborn child during a Fox News interview, calling the baby a "he?" It looks like it's true.

During an interview on Late Night with Jimmy Fallon, the host coaxed Ali Larter into giving up the goods. Fallon asked her to choose a pink or blue baby jumper.

Larter snatched the blue material proclaiming, "We're having a boy!"

Here's where the story gets a little naughty on Late Night with Jimmy Fallon. Jimmy Fallon congratulated Larter and the mom-to-be exclaimed, "Yes! I have a little penis inside of me."

This being late night, Jimmy Fallon penned Ali Larter's dirty-bird joke and mumbled, "That's what she said!"

What a way to truly reveal the sex of your baby. Love it.

Ali Larter's son is due to make his appearance in the winter.
