Jennifer Lopez PUTTIN' IN TWERK Miley Ain't Got Nuthin' On Me!

She's 23 years OLDER than Miley Cyrus ... but Jennifer Lopez was out to
prove she's the real TWERKING QUEEN during a booty-bouncing performance
in Miami. JLo and her big 'ol butt hit the stage at the "iHeartRadio Ultimate
Pool Party" on the CW last night ... and threw her glutes around like a 44-
year-old CHAMP during her new aptly-named hit, "Booty."So, the real
question ... how doMs. Lopez's twerk skills match up with 21-year-old Miley??
