She flew solo without her new husband James Righton but was beaming regardless.
Keira Knightley made a stunning appearance at the Toronto International Film Festival on Saturday where she promoted her recent film, Can A Song Save Your Life.
The 28-year-old actress was demure in a brightly coloured strapless frock, and her co-star Adam Levine didn't look too scruffy by her side either.
Keira's dress choice for the event boasted an elaborate forest-inspired design with purple flowers and pretty greenery.
She wore nude shoes and kept her jewelery to an absolute minimum, creating a beautiful natural look.
The Love Actually star pulled her brunette tresses back into a messy ponytail and flashed her signature smile on the red carpet.
Her co-star Adam Levine scrubbed up quite nicely in a sleek suit and crisp shirt and tie.
The Maroon 5 singer - who stars opposite Keira in the musical romance/drama - smiled as he posed at the premiere for the movie that sees him acting as well as singing.
The pair were also joined by fellow co-stars Catherine Keener and Shannon Maree Walsh as they welcomed their film to the Canadian festival.
Can A Song Save Your Life was written and directed by John Carney.
It tells the story of Gretta, played by Keira Knightley, whose celebrity boyfriend (Adam Levine) breaks up with her after a long-term relationship, leaving the singer to find success on her own.
She then meets record producer Dan, played by esteemed actor Mark Ruffalo, and forms a bond with him as she tries to make it in the industry.
Keira recently married her love James Righton - rocker of Klaxons fame - in a small ceremony in the South of France in May.
The pair kept things small and intimate with only 11 guests at the wedding and 50 at the reception.
In July, Adam became engaged to Victoria's Secret model Behati Prinsloo and the pair were recently seen house hunting in New York together.
