J. Lo Is Jenny From The Past In Clip For 'I'm Glad'

Singer/actress dons oversized sweatshirt, leg warmers for David LaChapelle clip.

Jennifer Lopez is saying This Is Me ... Then in her next video, and "then" is the '80s.

In the clip for "I'm Glad," which debuts April 8, J. Lo dances in an oversized sweatshirt and leg warmers, the unfortunate fashion choice for many in the era of Pac-Man and the Rubik's Cube. The video was shot last month by David LaChapelle, who has also recently worked with Justin Timberlake and Avril Lavigne.

Throughout the vid, Lopez strikes '80s dance moves, and the color, style and camerawork have a decidedly retro vibe.

The day the video premieres, Lopez will be interviewed on "Good Morning America."
