"The first time Mr Foxx became aware of this woman's absurd claims about an incident that supposedly occurred 16 years ago was when TMZ contacted his representatives," she added.
"The alleged incident was not reported to law enforcement in 2002, or at any other time in the past 16 years until last Friday because [it] never happened."
The police department lists the case as an open investigation, although the statute of limitations in Nevada is three years so has run out.
The woman said she was inspired by the #MeToo movement to file a police report.
She said she wanted a record of the alleged assault in case other accusers come forward.
