Jennifer Lopez keeps getting better with age.
The singer celebrated her 43rd birthday Tuesday in New York City with boyfriend Casper Smart, 25.
The former American Idol judge was all smiles as she stepped out in a nude and white floor-skimming dress on her way to lunch at Nobu.
Smart, in fitted black T-shirt, bright white pants and combat boots, led the birthday girl past paparazzi stationed outside the couple’s hotel.
Lopez has a lot to celebrate. The mother of two was recently ranked no. 1 on Forbes’ Celebrity 100 List, beating out Oprah Winfrey, Justin Bieber and Rihanna with her estimated income of $52 million in the past year.
