I'm not sure it ever left. In the battle of who's is bigger and who's is better Jennifer Lopez  is still Queen B-hind! This time she has doubled your pleasure by inviting Iggy Azalea onto the remix track of "Booty".

Jenny used to be the only booty on the block, but recently we got an array of booty to admire. Today's selection of juicy doubles includes Nikki Minaj, Beyoncé, Meghan Trainor but (no pun intended) J-Lo certainly takes the cake!  To get the most out of this video please keep in mind that Jenny is 21 years older than Iggy. At 45 this hot mama looks better than ever, you go Glen Coco!
