She is known for her grungy and often downright messy style, but on Friday night Kristen Stewart proved she is worthy of the title Hollywood A-lister with a sexy red carpet look.

With her hair styled, her make up perfectly done and a sleek ensemble, all eyes were on Kristen when she stepped out a San Francisco for a screening of her film On The Road.

Choosing to accentuate her lips against her alabaster skin with bright red lipstick, the 22-year-old looked like the impossibly beautiful vampire she plays in Twilight: Breaking Dawn Part II.

Kristen donned skin-tight leather pants which were cropped just above the ankle, a white T-shirt and a blazer at the Vanity Fair screening of her new flick at George Lucas' Skywalker Ranch.

Upping the simply chic outfit's sex appeal, the actress added red patent leather heels.

Despite being released around the world throughout the year, Kristen's On The Road is only being released in America on December 21 - more than six months since it first premiered at the Cannes Film Festival.

沪江娱乐快讯：美国当地时间12月7日星期五晚，电影《On The Road》的成员在旧金山Skywalker Ranch举行了一个小型的私人放映会。当日镜头前最亮相的莫过于女主克里斯汀·斯图尔特了。大红色的嘴唇，只到脚踝上方的紧身皮裤外加红色的高跟鞋使她整个人看上去既性感又大方。从斯图尔特最近出席活动的装扮来看，她越来越有大牌明星的范了！

此外，参加这次放映会的除克里斯汀和该电影的其它两名男主角萨姆·赖利和加内特·赫德兰外，还有美国著名的大导演弗朗西斯·福特·科波拉。据悉，科波拉在1979年就买下了《在路上》的电影拍摄版权，但拍摄一直没有成行。直到2004年才最终选定了由巴西名导沃尔特·塞勒斯执导拍摄本片。《在路上》已经率先于今年5月23日起陆续在欧洲各国上映，而美国则要等到12月21日才能迎来该片的全面公映。
