Garrett Hedlund Channels Miley Cyrus, Smokes Up on the Street

Our above headline is possibly a little unfair to Miley Cyrus, but when actor Garrett Hedlund is seen on video smoking an unconventional-looking cigarette, which he INSISTS is not weed, on the street in Montreal, then, well ...

The video was shot in August, when Hedlund - who also stars in Tron: Legacy and Country Strong - was filming On The Road with Kristen Stewart.

Garrett Hedlund Smokes Up

As you can see, Hedlund pulls a lighter and a "cigarette" out of his pocket, lights it, takes two drags and passes it to some girl who happily partakes.

It could be any number of legal substances, yes, but you have to wonder ... and it's hard not to draw comparisons to the Miley Cyrus bong video.

Hedlund's rep did not default to salvia, but told TMZ it was surely NOT marijuana, adding, "He would never smoke pot in front of all the paparazzi."

What do you think? We can already hear Mila Kunis' take ... totally weed!
