Jennifer Lopez just turned 43 and we gotta say ... we don't think she's looked better. Ever.

The Bronx diva just released the video for her new single "Goin' In," featuring Flo Rida, which is on the "Step Up Revolution" soundtrack.

The video is a perfect match for the dance-heavy track, and it gives J.Lo the chance to show off her "In Living Color" Fly Girl moves ... all while baring her ridiculously toned tummy in the process!

And this lady is a mother of two! At least she gives us all motivation to hit the gym...

Watch the full video ab-tastic below.

We can most definitely see this one being a huge hit in the club. What about you?
