It’s no secret that Taylor Swifts loves Kendrick Lamar and during a visit to K104′s Dede In The Morning Show in Dallas, Kendrick made mention that he is a fan of her new single “Shake It Off.” With that being said, they played the beat and the Compton emcee went to work.

What’s even more crazy is that today in celebration of her new 1989 album going Platinum with first week sales, Taylor Swift hopped in the car and rapped Kendrick’s “Backseat Freestyle.” Watch that clip below.
