India, Oct. 12 -- Jennifer Lopez has been on many movie sets over the past few decades, but she was not just the star during the filming of "Kiss of the Spider Woman" and was rather the "mentor."

Director Bill Condon, speaking to People magazine at the movie's New York City premiere on October 6, said Lopez "took Diego under her wing" as soon as shooting began.

"Diego came into this as a non-dancer," Condon said. "He's a great actor, but he shared his insecurity with Jennifer and she gave him a wonderful note."

That exchange, Condon added, sparked an immediate chemistry between the two.

"It was beautiful to watch them grow closer. As the movie progressed, they'd just spend more time together, " he recalled.

At 56, Lopez is no strange...
