Not even a "The Princeton Review" book editor can get away with criticizing Taylor Swift.

The SAT prep book used one of Swift's lyrics (as well as lyrics from Katy Perry, Whitney Houston and Lady Gaga) as examples of bad grammar "in real life."

There was one problem though - they got Swift's lyrics wrong.

One Swiftie caught the mistaken lyric that read "Somebody tells you they love you, you got to believe 'em" from the song "Fifteen."

The Swift lyrics were really supposed to read: "Somebody tells you they love you, you're gonna believe them."
When a fan posted a picture of the misprint on Tumblr, Swift saw and immediately called Princeton out.
"Not the right lyrics at all pssshhhh," Swift wrote. "You had one job, test people. One job."
