Jennifer Lopez and Marc Anthony
In the Marc Anthony-Jennifer Lopez
partnership, there's no question as to who's in charge.
"She's always been the boss! I don't know what's changed," Anthony, 38, told PEOPLE at Tuesday's Los Angeles premiere of the couple's movie El Cantante
, which Lopez, also 38, also produced.
"That's the first thing a man has to know," he says. "Absolutely, no question about it."
In the film, Anthony portrays Puerto Rican salsa pioneer Hector Lavoe, and Lopez plays his wife Puchi. Do Anthony and Lopez – married since June 2004 – share their screen characters' passion?
"Absolutely, we're passionate," Lopez told PEOPLE. "We're all passionate in a different way."
The couple will again join forces when they tour together
this fall – a first for them, and the first time Lopez does a live-concert road trip.
"I think we'll travel in the same bus, but we'll get ready in separate buses," said Anthony, before his wife quickly interjected: "Only because I have hair and makeup and all kinds of people. And then when he starts getting ready, he takes hours." The pair laughed.
"I nap up to 15 minutes before I go onstage," Anthony admitted. Fortunately, his wife plays by his rules: "So I can't make noise when I'm getting ready," Lopez explained.
The tour kicks off Sept. 29 in Atlantic City, with Lopez already having picked up tips from her constantly touring husband.
"I had a tutorial for two-and-a-half years now," she said. "I went on two tours with him from beginning to end. I saw every single show. So I'm like ready. I'm ready."
And do they think the couple that works together and plays together can manage to stay together? "We wouldn't put ourselves in this position if it was going to cost us in any way," he says. "We truly enjoy each other."
