Amanda Seyfried showed off some side-boob at the Los Angeles premiere of her upcoming film Lovelace, in which she plays porn star Linda Lovelace.

Seyfried, 27, wore a short, beaded Gucci halter dress with strappy black sandals. She wore her hair up and wore black smoky eyes.

E! Online notes she ditched the bra and let it all hang out on the side.

Seyfried said of playing the Deep Throat porn star, “There was the added challenge of the responsibility of playing someone who really existed and reiterating her story and her feelings on her life, because people just pigeon-holed her and she was defined by one thing."

Lovelace, who gained mainstream attention in the ‘70s thanks to a review in the New York Times, went on to pose in Playboy, Esquire and Bachelor during that decade.

Entertainmentwise reports in the ‘80s, she worked with Gloria Steinem on the Women Against Pornography movement.
