Jennifer Lopez looks smokin' hot in sheer dress at 46th birthday celebration in Hamptons
This is 46?!
Jennifer Lopez didn't look like she had aged a day when she stepped onto the red carpet at club 1OAK in Southhampton, New York.
The "Booty" singer showed hers off in an LBD that was more little than dress -- the skintight number featured a low neckline, numerous cut-outs and sheer panels.
Let's be real -- the frock was more bits of fabric than a full dress, but Lopez clearly pulled it off. She completed the look with strappy sandals, silver accessories and white nails.
Take a look at these photos of J.Lo through the years:
The mom-of-two walked into the party hand-in-hand with boyfriend Casper Smart, who was dressed smartly in a baby blue suit jacket, white button-down and navy pants.
J.Lo definitely enjoyed her party, dancing and even getting behind the DJ booth at one point.
Earlier in the afternoon, the couple celebrated Lopez's big day with her kids -- 6-year-old twins Max and Emme with her ex-husband Marc Anthony -- on a boat in the Hamptons.
Lopez and Casper originally called it quits in June 2014 before rekindling their romance a few months later, kicking off this past New Year's together in Las Vegas.
The actress-singer-entrepreneur's actual birthday was on Friday, which she celebrated with a cheeky Instagram post of Marilyn Monroe.
