LOS ANGELES (AP) — Just because Shia LaBeouf appears completely nude in the new Sigur Ros video and has said he’s willing to perform real sex acts in Lars Von Trier’s upcoming “The Nymphomaniac,” that doesn’t mean he’s going through an exhibitionist phase.

The 26-year-old actor says he’s “not choosing to be naked all the time” and that he “didn’t get into (acting) to be a porn guy.”

“We were just playing characters,” he explains.

Still, the 8½ -minute video for “Fjogur Piano” shows the “Transformers” star naked and caressing the bare breasts of his female co-star. He said people have been responding well to the video so he feels “quite confident” about his performance.
