Here's another name to add to the Taylor Swift song speculation list: Tyson Ritter.

A source told Celebuzz that Taylor met The All-American Rejects frontman in December 2011, after she dated Jake Gyllenhaal and before she dated Conor Kennedy. They reportedly bumped into each other backstage at the CMT Artists of the Year Awards.

This insider said they saw each other over a few months, but things were "super-casual." It ended over what sounds like lifestyle differences. “He wasn’t into her world and hurt her,” the source told Celebuzz. “He just stopped calling. He kept it very quiet because he isn’t a very public kind of guy. He’s so private, and he wasn’t into the glitz and glamour and attention-seeking like Taylor was. He’s more laid back and chill.” He's now dating actress Elena Satine after reportedly reaching out to her on Twitter.

So it's possible Taylor wrote something about Tyson, perhaps "I Knew You Were Trouble" is about him instead of John Mayer. That's supposedly what his friends think...
