Jennifer Lopez was looking hot and cool all at the same time at the San Juan, Puerto Rico film premier of El Cantante.

Should be interesting to see hubby, Marc Anthony, and Lopez in this story that semi-mirrors their lives. He's a singer that makes it to the big time and she's the little woman behind the man. Okay, well, maybe it just mirrors his life a little. We know that Lopez is in no way the little woman type. The film is due out in early August.

Anywhoo, check out this wowie! earrings she's got on, platinum "Caviar" earrings by Lorraine Schwartz. Now, this is when it's okay to not wear a necklace.
