Cardi B & Offset Sued Over Nonpayment for Mansion in ‘Like What’ Video

3:14 PM PT — Cardi B is speaking out against the lawsuit, saying she’s going to fight it in court.

Cardi just broke her silence on social media, saying in part … “IRON YOUR BEST SUIT BITCH I’ll see you in court!!!!”

Cardi B is denying she and Offset didn’t pay to use the mansion, and she says she has receipts. She says she paid the homeowner $10,000 for 24-hour use of the home, and paid a realtor more when they went over time.

Cardi adds … “And this is not the realtors fault…they been trying for months to settle this. Its them greedy owners wit their ugly ass house.”

Cardi B and Offset might need to cough up some “Money” … we’ve learned the estranged spouses have been sued for nonpayment for the mansion used in one of their music video projects.

In new court documents obtained by TMZ … the owner of the property featured heavily in Cardi’s “Like What” music video — which Offset directed — is alleging the twosome lied about their filming plans … leading the homeowner to give them free use of the manse.

As the plaintiff put it in the docs … Cardi, Offset and their team knew they’d have to shell out a chunk of change to film at the prestigious Beverly Hills residence for a music video … so, instead, reps for the couple told the owner an unnamed client hoped to film a TikTok video at the home.
