Jennifer Lopez borrowed Nicole Scherzinger's X Factor press shot dress and Mariah Carey's hair from circa 1991 to arrive at a party celebrating her world tour.
But if you steal someone else's style you'd better do it with aplomb. Or at least with maximum volume. Hence we have to introduce the Not-Quite-A-Poodle-Perm Half Ponytail Of Slightly Awkward Dimensions to the pantheon of celebrity hairstyles.
We imagine the pre-party situation ran approximately as follows:
JLo: MORE VOLUME
Hairdresser: But if I make it any bigger you might look a bit... silly?
JLo: Do I pay you to think or do I pay you to VOLUMISE?
Hairdresser [with a world-weary sigh]: To volumise.
JLo: EXACTLY. And make it taller too.
