25 Things J.Lo Did This Year!

Jennifer Lopez and Marc Anthony Show America How to Salsa on 'Idol!'

On the two-hour American Idol finale in May, J.Lo and her then-husband Marc Anthony brought the crowd to their feet with an explosive performance of "Aguanile" — a song by Hector Lavoe that they also covered in their 2007 biopic, El Cantante based on the famous salsero's life. Marc started off the performance by singing alone on stage — and his vocals were incredible! — but it was J.Lo who stole the show with her booty shaking and killer dance moves! Now THAT's how you salsa!
