Makeup-free Selena Gomez looks downcast as she departs Toronto without on-again beau Justin Bieber

She was seen arriving in Toronto with her on-again boyfriend Justin Bieber on Saturday.

But just one day later Selena Gomez was looking downcast as she left the Canadian city on Sunday by herself.

The 22-year-old let her skin breathe as went make-up free for a flight out of the Toronto airport, after just one night in the city.

Where's Justin? Selena Gomez looked downcast as she left the Toronto airport by herself on Sunday after being spotted arriving with Bieber the day before

The Come And Get It singer wore tinted sunglasses, a loose top and black trousers for the outing as she stood tall in boots.

Selena has been travelling quite a lot to spend time with the Baby hitmaker, as she recently jetted back to New York after enjoying a short romantic break with Bieber in his native Canada.

But Selena was back at the pop star's side in Toronto on Saturday. The on-again, off-again pair were seen arriving at their hotel, perhaps to attend an event at the Toronto Film Festival.
