Though most rumors about Swift's relationships should be taken with a grain of salt, Page Six reported Wednesday that the two spent all night together in a booth at festival after-party hosted by the Weinstein Company and Grey Goose.
"It looked like they were on a date all night,” a source told the column. “It was like everyone else melted away.”
But Thwaites might have some answering to do. Radar Online alerted readers to the Tumblr page of the Aussie actor's home-country flame, Jessica Campion, whom he dated when they met on the set of soap "Home and Away."
Campion and Thwaites appear to have broken up when he left for the U.S., but she still wrote about her hopes for their relationship on her Tumblr as recently as August.
“Worst. day. ever," she wrote after fans pointed out rumors about her ex-boyfriend and Swift. She also reposted this note from a fan: “Don’t worry about it. her music is sh** anyway … and you’re prettier.”
