Kendrick Lamar is getting his flowers after rerecording his “Bad Blood” verses on Taylor Swift‘s rerecorded album, 1989 (Taylor’s Version). Swift, who released her rerecorded album on Friday, went to social media to show love to Lamar.

“Watching @kendricklamar create and record his verses on the Bad Blood remix was one of the most inspiring experiences of my life. I still look back on this collaboration with so much pride and gratitude, for the ways Kendrick elevated the song and the way he treats everyone around him,” she wrote. “The reality that Kendrick would go back in and re-record Bad Blood so that I could reclaim and own this work I’m so proud of is surreal and bewildering to me.”

1989 was first released in 2014.

“I don’t hate you, but I hate to critique, overrate you/ These beats of a dark heart, use basslines to replace you/ Take time and erase you,” Lamar raps on the “Bad Blood” track. 

In her social media post, Swift also showed a video of herself performing “Bad Blood” earlier this year on her Eras Tour.

“Every time the crowds on The Eras Tour would chant his line ‘you forgive, you forget, but you never let it… go!’, I smiled,” she wrote.

Swift’s rerecorded album also includes a few songs which were previously unreleased. The 33-year-old said these tracks are “From the Vault,” according to People. Swift has decided to rerecord six of her albums, BuzzFeed reported. 1989 (Taylor’s Version), is the fourth album she has rerecorded so far.

When Swift first released 1989 (Taylor’s Version), many people considered it to be her best work, the New York Daily News reported. Speaking with Howard Stern in 2017, Lamar reflected on making the original version with swift.

“With this particular record, it was me just vibing and catching her lyrics,” he said. “I didn’t want to get into her head too crazy. I just wanted to have my own inspiration and see where it took it. Fortunately, the vibe was right and it didn’t take too many takes and we was really locked in on the chemistry and we really felt what was going on when I was in the booth.”
