Jennifer Lopez Dances, Almost Gets Dropped on Video Set!

At 42, Jennifer Lopez still has a little fly girl left in her -- but almost went flying during her latest music video shoot!
J.Lo has been filming the video for "Papi" over the last few days in L.A. -- and yesterday showed off some impressive dance moves on set ... while wearing some high, Christian Louboutin heels.

Lopez definitely kept up with the dancers on set, but lost her balance when once of them picked her up mid-choreography and almost fell off his shoulders!
