Lopez embodied 1960s Hollywood glamour in a flowing, light blue Valentino gown that she styled with Harry Winston diamonds. The refined look was a welcome departure from Lopez's usual revealing red carpet ensembles -- though, don't get us wrong, we love a good jaw-droppingly revealing J.Lo red carpet look!

Rodriguez looked incredibly dapper in a classic black and white tuxedo.

The couple also delivered the night's cutest moment when the former Yankees star was photographed taking a photo of Lopez on his iPhone as she posed alone for the paparazzi.
