Kristen Stewart has arrived in Toronto for her first public appearance since her cheating scandal hit headlines.

The 22-year-old actress touched down in Canada where she'll be promoting her new film On The Road at the Toronto International Film Festival.

Kristen was seen cutting a glum figure in oversized spectacles and a dark leather jacket as she arrived at the airport.

Earlier in the day she was seen boarding an aircraft at LAX sporting a white T-shirt that seemingly belongs to her estranged lover Robert Pattinson.

The Twilight hunk was left broken-hearted when pictures surfaced of Kristen in a passionate clinch with married director Rupert Sanders.

Kristen has kept a low profile since news of the affair broke, while Robert has garnered much support from friends and fellow stars alike.

Kristen is said to have been "fretting" over facing the public at the film festival.

While Kristen is in Canada promoting her new drama film - which also stars Garrett Hedlund and Sam Riley - Robert will be at the MTV Video Music Awards (VMAs) in Los Angeles.

The British actor and co-star Taylor Lautner will be introducing new footage from upcoming The Twilight Saga: Breaking Dawn - Part 2.
