And just when you thought it wouldn't last. J.Lo and Casper proved us wrong! Which helped this duo secure the No. 5 spot on our 2012 hottest couple countdown. After the former "American Idol" judge divorced Mark Anthony, we were shocked to see that J.Lo quickly moved on with her much younger dancer beau. And it works! While Casper showed his support by starring in her music video "Dance Again" and helping with the choreography for her world tour, Jenny kept him close by spoiling him with lavish shopping sprees and trips around the world. Seems like a win, win. No?
