"I'm ready to go," Lopez, 34, told the newspaper. "I'm all good."
The entertainer said he thinks the part is a good one for him since "Zach is very focused, so am I."
"I love that the show is so iconic and such a strong ensemble piece," Lopez said. "And that it's got so many great messages. You don't have to be in show business to relate to the idea of striving for a dream."
Although Zach dances at the beginning and end of the show, he doesn't sing a solo, the Daily News noted.
"I can carry a tune, but that's it," Lopez admitted. "I'm not a dancer, I'm an actor who moves OK. But I'm a pretty quick learner. I work really hard."
