(NBC NEWS) — Adult film star Stormy Daniels sued Donald Trump Tuesday, alleging that he never signed the nondisclosure agreement that his lawyer had arranged with her.

The civil suit, filed in Los Angeles Superior Court and obtained by NBC News, alleges that her agreement not to disclose her “intimate” relationship with Trump is not valid because while both Daniels and Trump’s attorney Michael Cohen signed it, Trump never did.

Stephanie Clifford, known professionally as Stormy Daniels, signed both the agreement and a side letter agreement using her professional name on October 28, 2016, just days before the 2016 presidential election. Cohen signed the document the same day. Both agreements are appended to the lawsuit as Exhibit 1 and Exhibit 2.
