Taylor Swift: Find Out Her Secret Diss To Kendall Jenner In ‘Shake It Off’

When Taylor goes into her mid-song rap, she’s totally talking about Kendall and Harry! In “Shake It Off,” Taylor raps:

“My ex man brought his new girlfriend. 

She’s like ‘oh my gosh’ I’m just gonna shake.” 

“She has a line that is very specific to Harry. When she talks about her ex bringing his new girlfriend that’s Harry and Kendall,” a source reveals to HollywoodLife.com EXCLUSIVELY.

As we previously reported, “Shake It Off” was generally inspired by all of Taylor’s exes, but Harry and his once-girlfriend Kendall got a special shout out!

Right after Taylor’s diss to Harry and Kendall, she continues rapping with:

“And to the fellas over there with the hella good hair.

Won’t you come on over baby, we can shake, shake, shake.”

Do you think she’s talking about the other guys of One Direction there? Despite her breakup with Harry, Taylor’s still close with them (she even set Selena Gomez up with Niall Horan!).

This isn’t the first time Taylor has reportedly called out Harry. She dissed the 1D hottie during her VMA Awards speech in August, 2013. She also made fun of their once-romantic moment during her “22” video shoot. And remember that shade she threw on his birthday? Wait, one more: We’ll never forget when Taylor used a British accent to diss Harry during her 2013 Grammy Awards performance.
