Barbie has her barbie bling.

Nicki Minaj flaunted her massive wedding ring from husband Kenneth Petty in an Instagram video Wednesday, while showing off their spooky Halloween costumes.

And, the “Megatron” rapper wants everyone to know that she didn’t pay for it.

“Everybody said that you secured the bag, you married a multi-millionaire and you secured the bag,” said  Minaj, who was dressed up as Tiffany Valentine from “The Bride of Chucky.” The rapper stayed in character, mimicking Jennifer Tilly’s distinctive voice.

Petty, who matched his wife’s fly as serial killing doll Chucky, responded: “You know I just cut somebody’s (expletive) finger off for that ring,” as Minaj flashed her huge rock.

“You mean, I didn’t buy this ring?” she asked. Petty replied, “No, you didn’t buy that ring!”

Her hard-to-miss ring is from New-York based jeweler Rafaello & Company.

“Congrats to the King and Queen, We wish you both lots of love and happiness together,” the company wrote. “Thank you for trusting us with designing and making these very special pieces for you both. @nickiminaj.”

Here’s a closer look:

Minaj, 36, announced her marriage to Petty, 41, on Instagram last week following nearly a year of dating. She shared her marital bliss with a video of matching “Mr. and Mrs.” mugs and coordinated “Bride” and “Groom” baseball caps.

 “10•21•19,” the rapper captioned the footage, appearing to reference the lovebirds’ wedding date.
