【Watch Millae: Good Brother Online】

And with a single plate of cookies,Watch Millae: Good Brother Online two of the world's biggest pop stars declared peace.

Katy Perry waved the sweetest white flag on Tuesday night when she uploaded an Instagram of a plate of cookies with "Peace At Last" spelled out in red frosting. The countertop kicker? She tagged none other than her ex(?) pop nemesis, Taylor Swift.

In addition to the tag, she also wrote "feels good 🧡 " in the caption. The location? "Let's Be Friends." If clicked, it drops a pin on the map in Monterrey, Mexico. Interesting.

Adding fuel to the fire, as she does, Swift commented 13 pink heart emojis.

Like a suitcase on vacation, there's a lot to unpack here. Before we do, though, let's quickly take a jaunt down memory lane.

The feud between Katy Perry and Taylor Swift dates back to 2014, when an alleged falling out occurred because both pop stars wanted to have the same dancers on tour with them. Swift even told Rolling Stonethat her song "Bad Blood" was about another female pop star, explaining, "She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me."

A day after the interview was released, Perry posted a cryptic Mean Girls-esque tweet, prompting fans to theorize that it was about Swift. Fast forward to 2017, during Perry's infamously rocky release of her album Witness, she brought up her feud with Swift, saying, "I'm ready to let it go."

A year later, in May of 2018, Perry sent Swift a literal olive branch on the first night of Swift's Reputation tour. The plant seemed to signify that amends had been made.

This Tweet is currently unavailable. It might be loading or has been removed.

Now, in 2019, both singers are getting ready to release new albums, so the timing of their plated partnership is raising a lot of questions.

1. Does this mean there's a collab coming?

Perhaps the biggest head scratcher here is whether or not this plate of baked goods means that the two have been in the studio together. Personally, I'd like to believe that, yes, they have. And yes, if they recorded something, it's going to be the bop of the century.

2. Who baked the cookies?

Swift is known to be an avid baker, so it's likely that she provided the feud-ending dough and beef-is-over oven.

3. Are they at Taylor's house or Katy's?

This is a tricky one, because I'm almost positive marble countertops are a standard in pop star homes. However, a quick zoom will show a marble lazy Susan, covered with polaroids. Given Swift's obsession with polaroids, it's more likely that she is the owner of a marble lazy susan piled with polaroids.But that's just a marble inkling I have. A rare glimpse into Swift's Beverly Hills home during her 73 Questions interview with Voguereveals some very similar marble counters in the singer's kitchen. Just saying.

4. What kind of chocolate chips did they use?

My gut says Toll House.

5. Is this just a stunt to get publicity?

If it is, it's working. Again, both arecoming out with new music, so it wouldn't be surprising if this is their way of getting everyone hungry for a duet.

6. Have they been secretly hanging out all this time?

Honestly, probably! Swift has been known for keeping a very, very, verylow profile recently, so it's easy to see her sneaking off to Perry's house, perhaps in a suitcase.

7. What if there's cyanide in the cookies?

I had to ask.

8. Who else was in the room where it happened?

Orlando? Joe? The Haim sisters? The possibilities are literally ENDLESS.

9. Why does the photo's location tag lead to Mexico?

While I'm pretty positive that this is just a case of using a random location tag for the name of it, we can't ignore it. Though, on second thought, it is Perry's post, not Swift's, so it's probably a meaningless coincidence and not an Easter egg.

10. Did they feed any of the cookies to Swift's cats?

Probably not.

11. Did they enjoy a glass of wine with their peace meal?

Probably.

12. Did they listen to their new singles and dance around the kitchen in the refrigerator light?

It's entirely possible.

13. Is this the beginning of a beautiful friendship?

I hope so!

I'm going to keep the defibrillator close, in case they do end up doing a collab. Because if that happens, my heart will surely stop.
