Katy Perry and Chief Keef worked it out on the remix.

The pair released a remix to Perry’s 2013 song “Legendary Lovers” on Thursday, 13 years after Keef threatened to “smack” Perry during an online beef.

Perry shared a TikTok video of the duo dancing and singing along to their song, with the caption, “LEGENDARY LOVERS OUT NOW @ChiefKeef.”

The “Roar” singer, 41, and the rapper, 30, merged their respective songs “Legendary Lovers” and “Save Me” for the remix after both tracks went viral on the social media platform earlier this year.

The pair sparked collaboration rumors on Wednesday when Keef’s record label, 43B, posted an Instagram Reel of the artists chatting in a parking lot while surrounded by a group of people.

“#Chiefkeef & #Katyperry link up finally,” read the upload’s cryptic caption.

That same day, Perry shared a TikTok of herself and Keef having a “legendary link up” as they shook hands to the sound of their remix.

Another TikTok from earlier in the week showed Perry sitting on a couch to meditate and was captioned, “attempting to summon Mr. Keef.”

The duo, notably, clashed on social media in 2013 when Perry shaded Keef’s song “Hate Bein’ Sober,” which featured 50 Cent and Wiz Khalifa.

“Just heard a new song on the radio called ‘I Hate Being Sober’ and I have serious doubt for the world,” Perry tweeted at the time.

In response, Keef — whose real name is Keith Farrelle Cozart — tweeted that Perry can “suck skin off my d–k.”

“I’ll smack the s–t out her,” he added in another scathing message.

Perry later publicly apologized to Keef.

“Mr. Keef! I’m sorry if I offended you. I heard a lot of people guesting on the song & didn’t even know it was you in particular,” she wrote via Twitter (now X).

Perry released “Legendary Lovers” as part of her fourth studio album, “Prism,” and Keef sampled the song for “Save Me” in 2014.
