JENNIFER LOPEZ LOOKS STUNNING AS SHE CELEBRATES HER 46TH BIRTHDAY

This is how we want to look when we grow up!  Still stunning: Jennifer Lopez celebrated her 46th birthday in a rather racy ensemble on Friday night.  The Grammy winner looked fierce in a racy black Bao Tranchi cutout dress with an open back and sheer paneling on the sides to show off her underwear-free booty. 

Lopez managed to distract fellow guests from the fact that she had turned another year older by wearing the outrageously racy dress.

The singer hit the nightclub's dance floor and enjoyed a cake from her longtime manager Benny Medina. "She was dancing all night, and she looked amazing," a source tells Us Weekly. 

At one point guests were incessantly taking photos of Lopez, and her on-off love Casper Smart stepped in to save her. The source tells Us that Smart told the guests to leave Jenny From the Block alone so she was free to dance and have a good time.

 She posed with pals including French Montana and Natasha Bedingfield in a VIP area before heading out to party. Who knew they were such good pals?

In less than five decades the star has managed to conquer everything from the album charts to the Box Office.
