Cardi B's husband Offset bought her a new $1 MILLION chain for her birthday. And Cardi wore the chain to the club last night.

The Chain - which has more than 1,000 clear and pink diamonds in it - is valued at more than $1 MILLION.

The “I Like It” rapper, 26, showed off her post-baby body in a plunging metallic jumpsuit three months after giving birth to daughter Kulture Kiari, and accessorized her look with lots of personalized diamond jewelry.

Cardi wore custom-made diamond Pristine Jewelers earrings with her daughter’s name across the hoop. She also wore a diamond-covered bracelet with a “K” charm in honor of her daughter — as well as an extravagant diamond encrusted chain necklace with her own name.

And that's not the ONLY gift that her husband gave her. In addition to the $1 MILLION chain, Cardi was given a $500K new Lamborghini jeep. Cardi was the first person in North American to own the new Lambo jeep.

Here are pics of her new chain:

Offset threw Cardi a STAR-STUDDED birthday party, too...Cardi had to put her own spin on the evening, ending the night with an Insta vid thanking Offset for the event...but also complaining that she was hungry, saying, "Hubs told me he was going to take me out to dinner, and I appreciate the surprise birthday party and all that...but I'm fucking hungry right now."
