Lily Collins gets the giggles on the Mortal Instruments: City of Bones set in Toronto, Canada on Tuesday afternoon (August 21).

The 23-year-old leading lady was scene running down the street, checking on a cyclist who fell over and chilling out with Robert Sheehan, who plays Simon.

Set in contemporary New York City, Mortal Instruments: City of Bones follows a seemingly ordinary teenager, Clary Fray (Collins), discovers she is the descendant of a line of Shadowhunters, a secret cadre of young half-angel warriors locked in an ancient battle to protect our world from demons.

FYI: Lily is wearing Diesel USA‘s MyGuy 800M jeans.
