Does this woman ever AGE?!

Jennifer Lopez was only a couple strips away from being in her birthday suit as she celebrated her 46th year on Saturday, July 25, at 1OAK in Southampton, N.Y.

The stunner strutted into the club in a dress with so many cutaways that we aren't quite sure what was holding the whole thing together!

On top of all the skin-baring sections, the dress also featured sheer paneling down the sides, meaning that it had to be worn commando. It's a wonder her date, Casper Smart, wasn't tripping all over himself.

Inside the club, the birthday girl was treated to an all-night party with cake and a toast from her longtime friend and producer Benny Medina.
