The Jenny From the Block hitmaker, who is known for her curves, wasn't sure about the song when she first heard it, even though her manager and handlers insisted it was the perfect tune for her to record, so she took a rough mix home with her to give it another listen and was stunned by her kids' reactions.
She says, "Everybody in the studio is like, 'This is the type of song that J.Lo needs to do', and I was like, 'Never in my life will I do a song called Big Booty!'
"I always take stuff to my car afterwards and kind of live with it and listen to it... so I'm in the car with my twins, Max and Emme, who were five at the time, and I'm listening to a bunch of songs and the minute they hear, 'Big, big booty 'cause you got a big booty' they went crazy. I don't know if they thought they were saying a dirty word but they loved this song, and because they loved it I recorded it.
"My son has a very good ear; he could be the next (music mogul) Clive Davis... We'll be in the car and listening to the radio and flipping through channels and all of a sudden he'll be like, 'Go back...!' He can pick on a first listen, only the big, big smashes."
