Rumor alert: Lively and Reynolds ... and Gosling

Surprise, surprise.

Rumors are already swirling that another woman might have been the catalyst for Ryan Reynolds and Scarlett Johansson‘s not-so-shocking-split. The woman? None other than Reynolds’ “Green Lantern” co-star Blake Lively.

Reports that the two were getting cozy recently surfaced, and will likely continue since the press tour for “Lantern” kicks off in early 2011 and the pair will be spending more than a little time together.

Idle gossip, we say, since it’s pretty much a given that the tabloids will link Reynolds to any female he’s been in close proximity to lately.

The leggy Lively, 23, also has been recently linked to the more cerebral Ryan Gosling, reportedly hanging with him all night at the NYC premiere of his sultry new flick “Blue Valentine” last week.
