Jennifer Lopez is really feeling the Holiday spirit.

In a video posted to her YouTube page, Lopez invited her fans from all over the world to be a part of "the biggest Christmas gift ever." In the homemade clip, the superstar and her young twins Max and Emme encouraged J.Lo's 13+ million Twitter followers and 17 million Facebook fans to donate at least one dollar through December 17 (via Omaze) that will later be split evenly between three worthy causes: Children's Hospital Los Angeles, The Boys and Girls Club of America, and The Red Cross.

In exchange for one lucky fan's generosity, one giver and a pal will receive airfare and a hotel room to Lopez herself backstage in Puerto Rico after the last show of her Dance Again World Tour.
