Jake, schmake!

Taylor Swift didn't let her recent split from Jake Gyllenhaal get her down at Wednesday's People's Choice Awards in L.A.

The single-again singer, 21, put on a brave face at the bash -- and while ex Gyllenhaal, 29, didn't show, two other recent loves were in attendance.

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.

Backstage, she bonded with BFF Selena Gomez, Ellen DeGeneres, Drew Barrymore, Efron and many other stars.

Still, an insider close to the Speak Now singer told Us Weekly she is "really upset" by the Gyllenhaal breakup. "We told her not to move so fast with this but she didn't listen," the source adds.

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.
