Calm down, people. Taylor Swift will not be writing any songs just yet about Brenton Thwaites. After the singer-songwriter, 23, met the handsome Maleficent actor, 25, at a Toronto International Film Festival bash earlier this week, rumors quickly spun out of control that the flirty, talkative twosome had already embarked on a romance.

"Taylor thinks all these rumors about her and Brenton Thwaites are completely ridiculous," a Swift pal tells Us Weekly exclusively. The "I Knew You Were Trouble" songstress was introduced to Australian up-and-comer Thwaites the evening of Sept. 9 at a private bash hosted by movie mogul Harvey Weinstein.

"Harvey Weinstein took Taylor to his table and sat her next to Brenton," the friend explains of the pair, seen laughing and talking animatedly during the soiree. "They had a nice time talking but no numbers were exchanged. A photographer asked to take their picture and they said yes."

Not that Swift didn't enjoy her time with the Blue Lagoon: Awakening hunk. "She did think he was nice, but how could you be dating someone when you only just met them five minutes earlier?" the source scoffs. "They are definitely not dating."
