Taylor Swift was seen getting chummy with actor Brenton Thwaites at the 'One Chance' screening in Toronto on Monday, Sept. 9.

One of her songs is on the soundtrack so she was there for the hang. That's when she got cozy with the handsome Thwaites, sparking romance rumors.

Local sources say that Swift, 23, and Thwaites, 24 and an Aussie, chatted for an hour, making each other giggle. He had his arm around her back and she touched his leg, which lead a source to say that they "seemed very into each other."

Anytime Swift hangs out with a dude, her critics and gossipers are ready to send her down the aisle, a fact that she herself acknowledges.

Another source played down the possible romance angle, saying that Swift made the rounds at the event. The insider said, "She talked to several people, and he was one of them."

So before we sound the alarm bells on a new Swift romance that'll go south in a few months and inspire a bunch of songs, take that into account.
