PHOTOS: Jennifer Lopez Does an About Face in NYC

Jennifer Lopez may be 40, but the sexy singer/actress and mother of two looked just fantastic last night at the launch party for makeup artist Scott Barnes' new book About Face. J.Lo showed off her famous form on the red carpet at Provocateur at The Hotel Gansevoort in New York City. Next up for Jennifer, who is still being wooed by the producers of Glee, is film The Backup Plan, slated to open in April, right around the time her new album, Love? is scheduled to finally go on sale.
