Well, maybe she's NOT dancing for you, but she's giving us all a sneak peek at her upcoming video for the single "Dance For You" from her latest album 4.

The now pregnant songstress, dancing in skimpy lingerie in a '40s film noir setting, is certainly showing no signs of a baby bump in this clip.

Looks like Jay-Z's 30-year-old wifey was busy filming numerous videos before getting pregnant. First she shot the video for "Love On Top," then "Party" and now this one.

The full-length video will be featured on the deluxe edition of Beyonce's "Live at Roseland" DVD. No one can say this mama-to-be isn't a hard worker.
