Today, Taylor Swiftofficially became the first solo artist to sell a million copies of an album, doing it with her new 1989 LP in just one week. Among her (at least) one million fans in the US is Kendrick Lamar, who's recently revealed his fandom with two takes on her hit single "Shake It Off" (currently number 2 on the Hot 100).

First off, in a recent interview with The FADER, Lamar was recorded singing the song and saying "I love that song." Listen to that below.

Then, he freestyled over the track during a recent radio interview. That's below.

Of course, this all comes after T Swift recorded herself lip-syncing along to King Kendrick's "Backseat Freestyle."
