Jaimie Alexander's sexy frock deserved star billing.

Eyes were cast upon the 28-year-old actress when she appeared at Friday's photo call for The Last Stand in Rome, Italy - and it was clear she outshone her famous cast mate.

For once again Jaimie stole the spotlight from aging action star Arnold Schwarzenegger, 65, who is making his first big screen comeback in a decade.

Jaimie can hardly be blamed for the phenomenon, which has occurred at every premiere and press event for the movie thus far.

As popular as Arnold and his co-star Johnny Knoxville are, the five-foot-nine actress has proven hard to compete with on the red carpet.

Who's the star now? Arnold might get top billing, but Jaimie seems to be getting most of the attention

She certainly wowed the crowd in Rome, wearing a sapphire velvet dress with plunging neckline and sheer side panels that showed off her slender waist.

Jaimie completed her look with a pair of matching blue high heels and minimal jewelry that included a delicate necklace and sparkling diamond ring.

Posing next to her with his hand gingerly on her waist, Arnold seemed a trifle uncomfortable in his designer grey suit.

Johnny, on the other hand, was decked out in dockers, a red sweat shirt, denim jacket and red Converse trainers.

Whimsical: Johnny Knoxville's outrageous ensemble was eye-catching, but no match for his beautiful co-star Jaimie

But even that whimsical ensemble couldn't outshine gorgeous Jaimie, who is dating Twilight star Peter Facinelli.

The thought of working with Arnold was daunting at first for Jaimie.

She told Totalfilm.com: 'You know, the thought was intimidating, because I didn't know what to expect, and then I met him, and I was like, "Oh, he's so chilled."

'He's really laid back and very friendly, very outgoing and just easy to be around. He doesn't walk around like he's better than anyone or anything like that,' she continued.

There she goes: Jaimie wowed the crowds at The Last Stand's premieres in Los Angeles on January 14 and in Germany on January 21

'He's very much a relaxed human being and throughout shooting, on the days that I was there on set and we were working, we would all sit down and eat lunch together.'

The Last Stand is Arnold's first leading role since Terminator 3: Rise of the Machines in 2003.

The story of the modern-day Western revolves around drug cartel leader Gabriel Cortez, who escapes a courthouse and heads to the Mexican border.

He ends up in the sleepy town of Sommerton Junction, only to face Sheriff Ray Owens (Schwarzenegger) and his inexperienced staff.

The movie was released worldwide on January 17 and in the US on January 18.
