Glee's Cory Monteith and Twilight hunk Taylor Lautner both attended the fest. While it's not known whether Swift and Lautner, 18 (they dated for three months in 2009) exchanged words, the country crooner and Monteith, 28, exchanged a friendly hug backstage.
But wait: Who was Swift's male companion for the evening? That would be Austin Swift -- her brother.
Swift was in high spirits throughout the night. Seated just a few rows in front of Zac Efron (who parted ways with Vanessa Hudgens last month), she hugged a staffer and obliged fans with photos and autographs during commercial breaks.
Why did the Love and Other Drugs hunk call it quits? "Jake cares about her, but [the publicity] was a lot for him. He wants to keep his private life private, and that’s hard to do dating Taylor," a Gyllenhaal confidante explains.
