Jennifer Lopez and Marc Anthony rock the stage in Puerto Rico.
Jennifer and Marc were in Puerto Rico together this weekend. Marc was performing at a concert at the coliseum and Jennifer joined him on the stage for a duet of the song “Preciosa". She also took some time earlier in the day to visit a pediatric hospital with her sister Linda.
Jennifer then jetted off for New Orleans where she's filming the final local auditions for "American Idol".
