Jennifer Lopez takes a quick, um, "SIT DOWN"
during her American Music Awards performance

Jennifer, babe, it AINT HOW YOU FALL, it's how QUICK you GET THE HELL UP!

Come to think about it, it may have been PLANNED! That's right folks, Jennifer Lopez prolly PLANNED to fall, just so the haters would come out and start HATING!  For real, we didn't think we'd ever see Mrs. Anthony move that fast, but girl was NOT PLAYING when she took a little spill during her performance at the American Music Awards.
