Jennifer Lopez at the Buddah Bar in Paris

"Stepping out for an enchanted evening, Jennifer Lopez hit up the Buddah Bar in Paris, France last night (October 15).

Joined by boyfriend Casper Smart, the “Waiting for Tonight” singer helped her sister Lynda celebrate her birthday with a swanky shindig that looked to be tres expensive!

Last week, J. Lo ended up giving the audience a little more than they’d bargained for when her top slid down during her concert in Italy.

Lopez also accidentally showed off her Spanx shapewear while prancing around on stage in one of her skimpy costumes. Oh La La!"
