Ashley Greene matches her sparkling smiles to her dress as she arrives at the premiere of Butter held at Roy Thomson Hall during the 2011 Toronto International Film Festival on Tuesday (September 13) in Toronto.

The 24-year-old actress wore a stunning Oscar de la Renta dress to the big event, where she joined costars Jennifer Garner and Olivia Wilde.

It was just announced earlier this week that Ashley will be starring in the title role of Olivia Twisted.

The flick is an updated tale of Charles Dickens‘ “Oliver Twist.” The movie will center on 19-year-old Olivia and a group of very capable street orphans. After accepting a kidnapping job, the group finds themselves smack dab in the middle of a turf war between two criminal factions.
