Cardi B is getting creepy and kooky with her latest Halloween costume.

On Sunday (Oct. 31), the 29-year-old rap superstar took to social media to unveil her stunning costume, a spooky reimagining of the sultry Morticia Addams from The Addams Family.

“MORTICIA ADDAMS,” Cardi captioned the gothic-themed gallery on Instagram, tagging fashion designer Natalia Fedner for her work on the impressive black metal dress.

“The outfit is entirely metal! It’s black chain,” the designer wrote in a separate Instagram post. “The corset is used making a special resin casting process.

In one spine-chilling photo, a pale-looking Cardi clutches onto a single red rose, while another pic features the MC leaning against a black hearse.

Fedner also gave a behind-the-scenes look at the making of the costume, explaining that it took a full week to create. “The black metal dress is also made using the 6-way stretch metal technique,” she wrote, giving a shout-out to Cardi’s stylist Kollin Carter. “For Cardi, I used the ‘spiderweb’ version of this technique as directed by her stylist, to give the look an extra Halloween twist.”

Cardi’s costume wasn’t her only weekend surprise. On Saturday, the rapper teased fans with a snippet from a new song. “SURPRISE!!!!!! I’m dropping a song on Monday on SoundCloud!!!” she tweeted alongside a 20-second audio clip of the vocals. “Nothing serious just something special for BARDIGANG… Here’s a lil taste.”

Cardi was recently featured on Lizzo’s newest single “Rumors,” which hit the No. 1 and No. 4 spots on the Hot R&B/Hip-Hop Songs and Billboard Hot 100 charts, respectively. Cardi’s 2018 album, Invasion of Privacy, debuted at No. 1 on the Billboard in 2018.
