Two years after their smash hit “Kiss Me More,” Doja Cat and SZA dropped their newest collaboration ⁠— a remix of SZA’s SOS track, “Kill Bill.”

Doja briefly teased the track on Twitter just hours before they released it.

“@sza sis… I did something bad,” she wrote. 

SZA responded via retweet.

“Jesus.. what is it,” she asked.

The original version of “Shirt” was supposed to feature the rapper, but SZA’s team had to pivot after Doja Cat had to undergo an emergency tonsil procedure.

“She had surgery, she had to have that emergency, like, vocal cord surgery and she wasn’t ready in the time that we needed to get the song done,” the singer explained on Hot 97 last year. “There was a crossfire between, I think, her management and my management and they had told us it was done, but it wasn’t actually done.”

At the time, SZA said the situation was confusing, though she was hopeful a chance to include Doja on SOS would present itself.

“It was just a lot of confusion,” she said, “but don’t know. I hope for the best, and I’m still, like, a major fan of her and her artistry. And I think she’s so incredible and I would love to get her on the deluxe [version].”

Their previous collaboration, “Kiss Me More,” received critical acclaim, earning the duo a Grammy Award for best pop duo/group performance and Grammy nominations for record of the year and song of the year.

Their “Kill Bill” remix could be just as popular. The original peaked at No. 2 on the Billboard Hot 100 chart in December.
