After catching some flack for her twerk-filled music video for the song, the ageless singer fired back at critics who said she was acting too young in it.
"This is good for women," she told The Insider on Yahoo!. "You have to know that you don't disappear after you're 28 years old. You can be here, you can be vital and young and sexy and feel good about yourself. You don't have to worry about competing with anybody. We weren't competing, me and Iggy in the video. We were co-existing in kind of a beautiful way and owning it!"
As for how J.Lo stays in such amazing shape, the singer said, "It's like anything else. You've got to live right. You eat right and you work out. Nobody can escape the hard work that it takes to get results on anything in life. All of us have to work hard at it and I definitely do."
One person who isn't criticizing her booty is her ex, Sean "Diddy" Combs. The hip hop mogul recently praised her derriere after watching the video, telling Access Hollywood Live her bum is "a work of art."
(Hmm. Well, like she said, it's definitely a work of working out, but we'd say her music is the real work of art!)
"It's something that will go down in history for real. It will," he said. "She's a great friend of mine, always will be my friend and I mean, that thing is just incredible, man." When asked if Kim Kardashian's butt came close to J.Lo's, Diddy said, "No way, no way. No diss to Kanye and Kim but that thing right there, that thing right there is something special."
