Songstress Jennifer Lopez has wowed the world with her incredible figure in the new music video for 'Booty' and her personal trainer Tracy Anderson has now opened up about how the superstar keeps in such amazing shape.

Speaking to Ryan Seacrest, she admitted that JLo's stamina and determination definitely help with her intensity:

"She showed up, she really brings it. She’s just a super-focused, amazing girl. And she shows up for her workouts and she does what I ask, and she looks pretty damn great, I think. She was an athlete, so she knows her body really well.”

"One of the things I find so beautiful about her as a woman is she doesn’t cut herself off to any of the things that make women really beautiful. There’s the mother in her, there’s the career woman in there, there’s the entertainer in there… within all of that, she also doesn’t feel so entitled that she doesn’t have to take care of herself. She actually really works out and works hard.”
