Tayor Swift reportedly flirted with Australian actor Brenton Thwaites following her appearance at the Toronto Film Festival on Sept. 9.

After attending the premiere of One Chance, Swift, 23, went to a private party at Soho House where she met Thwaites, 24. They talked for an hour in a booth together while "making each other laugh," an onlooker told Us Weekly. At the film festival to promote his flick Oculus, Thwaites "had his arm around her back" and "she touched his leg a few times. They seemed very into each other," the witness added.

The pair also posed for photos together at the party, with Swift wearing a white gown with side cutouts and Thwaites sporting a navy suit and a white shirt.
