Lily Collins in Houghton - 'The Mortal Instruments: City of Bones' Toronto Premiere

Lily Collins, who has been busy promoting the new movie 'The Mortal Instruments: City of Bones' (and quite fashionably, might I add), attended the premiere of the movie in Toronto, Canada.

For the event, Lily wore a (signature almost, at this point) backless white lace gown by Houghton.  Opting to keep things clean, Lily finished off the look with a delicate updo and shimmering lips.
