Cardi B is getting spooked by someone she admires.

The “WAP” rapper just got an unexpected package in the mail and its has “You” written all over it.

Cardi announced that she got a gift delivered to her NEW home address from a fictitious murderer.

She tweeted a photo of a navy blue hat that had “HELLO YOU” written on it along with a letter from Joe Goldberg.

She tweeted, “How Joe found my new house address ? 😳😳.”

The note started off, “HELLO, YOU… My stalking and killing may make me a certified freak, seven days a week, but it also brought me to… you.”

The note concluded, “Can’t wait to see you slaying in this hat, but I certainly hope you don’t disappear. Au Revoir, Joe Goldberg.”

Cardi and Penn first connected on Twitter and exchanged admiration for one another.

Cardi also reached out to Netflix about getting a cameo in S4!
