On the outside, Jennifer Lopez looks a lot like she did 23 years ago when she debuted as one of the Fly Girl dancers on “In Living Color.” At 45 she’s got the same gaze–the one that can go from steely to sultry to sweet in a matter of moments–and the same warm, welcoming smile. And she’s got the same curves, the ones that inspired hip-hop’s most famous ode to booty and 100 million YouTube views. At the top of 2015, Jennifer Lopez is well into a career renaissance. Her last album debuted in the Billboard top 10, and her last video broke the Internet when it dropped in September. Even better, she’s featured on the cover of Complex’s February/March 2015 issue!
