Former “Real Housewives of NJ” star turned turned porn queen Danielle Staub, was paid $25,000 up front to strip for Scores in NYC … but the deal went up in smoke after the reality whore reneged on her contract. And now, she’s getting sued for $375,000.

According to the lawsuit, filed in April, Danielle got $25,000 to appear in a full nude strip video back in November of 2010. And according to the suit, it was all part of an exclusive 3-year contract, which also required Staub to perform voice work … and even appear in a live video chat session on ScoresLive.com.

But after shooting the video for Scores, Danielle allegedly bailed on their deal out of nowhere … cutting off all contact with the company. And now, they are suing her for $375,000 … claiming breach of contract.

This whore’s life is the epitome of pitiful.
