Cardi B Received a Letter From You's Joe Goldberg, and It's Just as Creepy as You'd Imagine

You know those friendships where you see each other and the rest of the world fades away for a second because you're too busy jumping up and down and screaming out of excitement to notice anything else? Yeah, it looks like Cardi B and Penn Badgley know exactly what I'm talking about. In a resurfaced video of Penn promoting You with his costar Shay Mitchell, he casually brought up Cardi and how much he admired her second-nature relationship with social media, something his character Joe Goldberg needs to work on, to say the least.

"Cardi B is a great example of that," he said in the video. "She has such an authentic relationship with social media, and despite what many might judge as antics, I think she has an incredibly authentic relationship to that, and that's why people like her so much." Thanks to Twitter, Cardi finally caught a glimpse of the interview, and her reaction to Penn revealing he's a fan was unexpectedly enthusiastic.

"OOOOMMFFFGGGGGG HE KNOWS ME !!!," Cardi jokingly captioned a reshare of the tweet on Oct. 16. "OMMMGGGG!!!!!! Yoooo like I'm famous-famous." On Oct. 19, the tweet circled back around to Penn, who could only respond with a stunned, "I —." We're just as surprised and confused as you are, Penn, but as far as celebrity friendships go, we can't think of a better starting point than mutually raving over each other.

Oh, and did we mention that two days later, on Oct. 21, Penn and Cardi swapped their Twitter profile photos to pictures of each other? So, yeah, they're basically BFFs now. Shortly after changing their profile pictures, Netflix changed its description on Twitter to read, "Petition to get Cardi B to guest star in Season 4 of You!" Of course, Cardi was absolutely up for the idea and replied, "So it's episode 1 and I'm at Paris Fashion week shutting it down! I turn around and there stands YOU." So it definitely sounds like she's on board, and so are we.

Fast forward a couple weeks later and Cardi received You merch and a "WAP"-themed letter from Penn himself. "How Joe found my new home address? 😳😳" Cardi captioned a Twitter photo showcasing the merch, which included a baseball cap stitched with Joe's signature "Hello, you" greeting. Oh, and the letter is just as creepy as you expected. "Hello, you… My stalking and killing may make me a certified freak, seven days a week, but it also brought me to… you," the letter read. "Cardi B, you have a way with social media. You're meaningful. Substantive. I just like you. You're authentic and nuanced ... just as you are with your music. You keep me on my toes, the ones that are left, at least. You can't be caged in and it's refreshing." As for the letter's conclusion? It gave us chills. "Can't wait to see you slaying in this hat," it read, "but I certainly hope you don't disappear."
