Robert Pattinson was recently spotted shivering and looking sad, while shooting for his upcoming film "Life" in Toronto. The "Twilight" actor was seen strolling alone, as the snow drizzled down on the sets of the film. This has now led to speculations that Pattinson might have been missing his ex- lady love Kristen Stewart.

The picture from the sets shows Rob dressed in an overcoat, with his face hung in despair, reported Hollywoodlife. Since breaking-up with Stewart, the British actor has gotten real busy with various film projects. In "Life" the actor will be seen playing the character of a photographer Dennis Stock, who has been assigned with the task of clicking pictures of 1950s megastar James Dean. "Life" will hit the theaters in 2015 and is being directed by Anton Corbijn. Apart from Corbijn's project, Pattinson has a slew of films lined up for release including "The Rover" and "Map to the Stars."

Doing back-to-back films appears to be Pattinson's way of keeping his former lover's thoughts at bay.

The duo fleetingly reunited last year during Halloween and the couple was even rumored to be spending the Christmas and New Year Eve together. However, things did not work out between them, and the actor is said to have spent time with his family in London, reported the website.

Apparently, Pattinson's family is not very fond of Stewart as they fear that the latter will break his heart again. The former love birds started dating each other on the sets of  "The Twilight Saga". However, they called it quits when Stewart was caught cheating on Pattinson with the "Snow White and Huntsman" director Rupert Sanders.

Since then the duo has tried reuniting may times but things haven't worked out. Just like Pattinson, Stewart is also busy charting her career in Hollywood. She will be next seen in movie titled "Still Alice".
