Looks like Taylor Swift may have found the subject of her next chart-topping album, at least according to witnesses who saw her getting cozy with Australian actor Brenton Thwaites earlier this week.

Thwaites, 24, was at the Toronto Film Festival for the premiere of his movie 'Oculus' when he met Taylor at a private party on Monday night -- and sparks supposedly flew.

"[He] had his arm around her back," an insider told Us Weekly. "She touched his leg a few times. They seemed very into each other."

Then again, it may be much ado about nothing, because another party attendee reported, "She talked to several people, and he was one of them."

But our money is on something developing here. Thwaites may be relatively unknown in the US, but he's young, handsome and knows Angelina Jolie (they co-starred in the upcoming 'Maleficent'). Plus, it's been a while since Taylor had a boyfriend. She and Harry Styles split in January -- and hey, those hit songs don't write themselves.
