It's no secret that Taylor Swift and Katy Perry have had one of the biggest and most infamous feuds of the decade. Larry Busacca / WireImage It even culminated with the two releasing diss tracks — Taylor striking first with "Bad Blood" and Katy responding with "Swish Swish."

Lester Cohen / Getty Images, Steve Granitz / WireImage This has been a long time in the making: Back in May 2018, Katy sent Taylor a note and a literal olive branch as a peace offering (which Taylor posted on her Insta story). Instagram: @taylorswift The two have not interacted with each other since then (except for Katy liking an Instagram post in which Taylor spoke about being more political in the future back in October), spoken about the feud, or given any details about that peace offering. All was quiet on the Katy and Taylor front until two weeks ago, when Katy liked a tweet Taylor posted of her new cat, Benjamin Button. Twitter: @katyperry After Katy's like, Taylor then added Katy's new song "Never Really Over" to her "ME!" Apple Music playlist. Apple Music Then today, Katy posted this on her Instagram and tagged Taylor in it and put the location as "Let's Be Friends": View this photo on Instagram Instagram: @undefined I mean, "PEACE AT LAST" ❤️❤️❤️!!! Katy Perry/ instagram.com Are cookies the new olive branch?! Also, it's unclear if Taylor sent Katy the cookies or if Katy made them. She also captioned it with this: Katy Perry/ instagram.com Ugh, feels! To which Taylor replied: Katy Perry/ instagram.com LIKE, MORE FEELS!!!! Honestly, I love that these two are making it known that they have put all that behind them and that they're friends again!!! 😭😭😭 Kevin Mazur / WireImage Now I am left with one BIG question: Is this public declaration a clue that the two are in fact collabing on song for Taylor's new album?!
