Kristen Stewart gets some screen time in the first trailer for her movie “On the Road.” But she’s mainly eye candy, and one scene even fuels the rumor that she might appear topless.

The Twilight actress is definitely topless in one scene in the trailer. She’s sandwiched between hunky, also shirtless Garrett Hedlund and Sam Riley. The camera angle, however, is from the back.

Her sexy bare shoulders are visible but that doesn’t mean she’ll bare any more skin in the film. Studios are notorious for floating rumors that actresses will be revealing all to hype their pictures.

Jennifer Aniston has hyped her last three films that way.

But Aniston has never appeared nude on screen. Nor has Stewart, although she’s had some close calls.

Kristen came closest to nudity in 2007’s indie film “The Cake Eaters.” She plays a young girl who is part of a family that is trying to come to grips with a tragedy.

Stewart raised eyebrows when she showed off her trim body in a tiny white bikini while shooting scenes for “Breaking Dawn” in Brazil.

Her new movie is based on Jack Kerouac’s 1951 novel by the same name, which is considered to have helped spawned the ’50s Beat Generation. The cultural upheaval, in turn, helped pave the way for the ’60s counterculture.

In the movie Hedland plays Dean Moriarity and Riley plays Sal Paradise. The sidekicks decide to take a cross-country round trip to discover America. Stewart plays Marylou and Kirsten Dunst plays Camille.

The cast also includes Amy Adams,Viggo Mortensen, Steve Buscemi, Terrence Howard and Elisabeth Moss.

The film, directed by Walter Salles, will premiere at the Cannes Film Festival later this year. The role will be a marked contrast to her Twilight character Bella Swan.
