Jennifer Lopez's new video for "Dance Again" debuted during last night's episode of American Idol. The short piece features an amazing-looking J Lo in top dancing form. Her partner in the video is none other than her real-life boyfriend Casper Smart. Much has been made about Jennifer and Casper's steamy scenes, and "Dance Again" doesn't disappoint. The song's lyrics seem to allude to 42-year-old Jennifer finding love with 24-year-old Casper after splitting from Marc Anthony last Summer. Jennifer sings, "Who cares what they're gonna say? . . . I wanna dance, and love, and dance again." She and Casper have obvious chemistry — check out J Lo's new video!
