With Kristen Stewart in Canada busy filming her new movie On The Road we thought it was only a matter of time until Robert Pattinson was spotted visting his rumoured beau on set.

And lo and behold, it has been reported that Rob arrived in Montreal yesterday and headed to the set.

However, before we get too excited we need to consider the fact that Rob's best mate, Tom Sturridge (phwoar) has also been cast in the movie...

It is possible Rob was just visiting his friend but we'd like to think Tom was just a cheeky bonus on his trip to see his girlfriend, KStew!

A representative for Tom confirmed to GossipCop that he was starring in the movie, saying: "He is filming in Canada at the moment for On The Road".

Kristen and Tom have been spotted hanging out on the set and at the Four Seasons in Los Angeles last month.
