And she's looking good too!

Jennifer Lopez was a cool customer yesterday as she stopped by Saks Fifth Avenue in Beverly Hills to do a little shopping. She chose this coast's version over the east's!

The 45-year-old entertainer just got back in town after spending some time in New York City for fashion week, where she took the stage at Fashion Rocks 2014 on Tuesday to perform her new hit, Booty.

She didn't just sing about it but showed if off in some sexy outfits that had everyone talking, from her red carpet dress to her outfit on stage.

Judging from the looks of it, she's still got it!
