Say it ain't so! We have yet another couple to add to the 2009 breakup list!

After three months of dating, country cutie Taylor Swift and Taylor Lautner have ended their relationship. A source for Us Weekly says, "It wasn't really developing into anything, and wasn't going to, so they decided they were better as friends. There was no chemistry, and it felt contrived."

When Lautner flew out to Nashville for Swift's 20th birthday party two weeks ago, that's when their romance began to fizzle, and a source for the mag added, "He liked her more than she liked him. He went everywhere he could to see her, but she didn't travel much to see him."

While the two plan to stay friends, that's still gotta sting for the New Moon stud! Then again, I'm sure he'll find someone else to admire his perfect abs...
