Jennifer Lopez found it a challenge filming El Cantante alongside husband Marc Anthony, because their acting styles are so different.

The Wedding Planner star plays Puchi, the wife of Salsa king Hector Lavoe - played by Anthony - in the movie drama.

Lopez says, "We have very different acting styles. He's kinda a method actor, he likes to improvise. He says, 'Don't worry, just go with it.'

"I'm very disciplined. I know all my lines, I know all his lines.
