Jennifer Lopez turned 43 yesterday and she proves that she's still got it goin' on in her new video "Goin' In," featuring Flo Rida.

The new tune, off the Step Up Revolution soundtrack features the former American Idol judge showing off her curves and causing her own dance revolution.

One thing we found difficult to find in the clip is the singer's boyfriend, Casper Smart, who featured prominently in her video for "Dance Again" and directed her in Wisin y Yandel's latest video, "Follow The Leader."

J. Lo also brought the sexy to Vogue magazine in a sizzling swimsuit shoot back in may. Check out pics here.
