Tyga isn't the only rapper who can't (or won't) pay his rent.

Riff Raff is being sued by his landlord for $68,500 for unpaid rent and damage to a pad that includes a 40 gallon fish tank, a mini casino and other baller type amenities.

Now this isn't the 6,000 square foot Codeine Castle which Jody just bought in Las Vegas. He owns that property, so he is free to destroy it any way he sees fit.

So far no word from Riff's camp on the lawsuit. But given that all the big rappers are getting sued these days it just adds to Jody Highroller's sometimes questionable rap game credentials.
