Birthdays are supposed to be fun, but that definitely wasn't the case for Taylor Swift when she was celebrating her birthday and it's all because of one of her exes, Jake Gyllenhaal.
According to RadarOnline, Taylor was totally in love with Jake but everything went downhill after he supposedly didn't show up for her 21st birthday party back in 2010.
"The day before — all was set — he was coming, no issues. But the day of, she doesn't hear from him at all. No texts, no calls," their source said. "Taylor thought maybe he was planning some sort of surprise. He didn't show up and she locked herself in the bathroom and cried the entire night."
Luckily for her fans, something good came out of the incident — her hit song "Red," which her breakup with Jake reportedly inspired. As for the birthday incident? Evidently the song "The Moment I Knew" references what went down the night he didn't show up.
