Jaimie Alexander has been quietly making the red carpet rounds for her new film "The Last Stand," but there's no doubt her star power is increasing. The actress sizzled at the film's London premiere on Tuesday night in a low-cut, sequined mini dress.

Alexander is most known for her role as Jessi on the ABC Family series "Kyle XY." She also appeared in "Thor." She is currently dating "Twilight" star Peter Facinelli, Jennie Garth's ex-husband. Jaimie and Peter co-starred together on "Nurse Jackie" and met on the set of the film "Loosies."

"The Last Stand," also starring Arnold Schwarzenegger and Johnny Knoxville, hit theaters last weekend and fared poorly at the box office, making only $6.3 million.  That's just a short setback for Alexander, who has several films in production, including "Thor: The Dark World," "Savannah" and "Intersection."
