Holy Justin Timberlake: Jessica Biel Reveals Baby Bump!

Actress looks pregnant on the set of her new movie New Year's Eve

Whoa! Have Jessica Biel and Justin Timberlake been doing more than just riding bikes together?

After all, the actress was spotted with quite the burgeoning belly in New York City on Monday night.

Ah, but alas, upon further review it was quickly revealed that she was simply sporting a fake baby bump for a scene that was being shot for the upcoming ensemble flick New Year's Eve.

Of course, seeing how a source recently revealed that Jess and J.T. are "definitely back on," a real-life rugrat down the road for those two is certainly a possibility!
