Jaimie Alexander is tearing a page out the Gwyneth Paltrow playbook. The stunning actress (and girlfriend to Peter Facinelli) completely stole the show at the star-studded Hollywood premiere of her new film, "Thor: The Dark World." Nixing undergarments of any kind, Alexander, 29, donned a black Azzaro Couture gown that revealed more than it concealed: Reminiscent of Paltrow's "Iron Man 3" premiere dress back in April, Alexander's frock featured a see-through panel that went down from her neckline and slithered down to her ankles -- exposing her backside and just barely covering the rest.

The up-and-coming star wore her hair in an elegant updo and kept her makeup simple and fresh-faced, wearing silver, feather-shaped earrings and gold stilettos.

Dating Facinelli, 40, since the fall of 2012 (in the wake of his split with wife Jennie Garth), Alexander joked at a Hollywood bash last week about the "most romantic" thing that her "Nurse Jackie" costar ever did for her.

"I think that's too graphic, baby." Thinking of a more acceptable response, she said, "You're always holding the door for me."
