J-Lo's backstage demands...

Jennifer Lopez has one very simple request when making public appearances.

The 'On The Floor' singer has been deemed a diva, but J-Lo's recent demand wasn't exactly a prima donna one.

When J-Lo made appeared on Alan Carr's TV show, she simply asked to only drink from her own personal glass according to The Metro.

Gaga has her fancy tea cups, and now it would seem Jennifer Lopez has her "special" glass.

Jennifer Lopez is currently promoting her new album 'Love?' which is out now.
