Shania Twain is gearing up for her big screen feature film debut with a little help from her veteran co-star John Travolta.

“I think Shania is born to be on film,” the “Grease” actor tells ET Canada’s Matte Babel. “Her videos say that. Her videos are a knockout but I think this is such a beautiful role.”

ET Canada was on the set of “Trading Paint” in Alabama where Twain says acting feels totally natural to her.

“Well, it’s fun and it feels really natural,” the Grammy-winning Canadian superstar says, adding being on set with Travolta helped calm her nerves. “I thought I was going to be really intimidated.”

In the drama, two-time Oscar nominee Travolta stars as Sam, a veteran race car driver who learns to balance ego, family drama, personal relationships and competitive nature with his racing son. Cast as Sam’s girlfriend Becca, acting newcomer Twain says she was totally in awe of her co-star’s skills.

“Just watching him in the moment, this guy cries on the spot! Is this guy for real or what?! I am just really amazed,” she tells ET Canada. But she’s not the only singer on the set. Twain reveals Travolta “sings on the spot all the time.” Does this mean there’s a future duet between the two in the works?

“I didn’t reveal the little secret that we are thinking about doing a duet,” Travolta says. “‘I told him I was looking at you, she looked gorgeously beautiful,’ this song came right into my head, this is between takes. Shania said, “I love that song. That would be a good duet.'” “I wanted to do a duet album with him years ago,” Twain confirms.

Naturally, being on a movie set surrounded by cars makes the 63-year-old actor think of his “Grease” days.

“Music is a big part of my life and I miss doing it and, of course, if I want to have an effect on others I will break out into a familiar song,” Travolta teases. “I thought if I broke into ‘Grease  Lightning’, I bet it would cause a very good effect.” And he was right: “I did the whole thing, the whole crew went crazy, it was the perfect set up!”
