She said Strauss-Kahn called her in January that year to request an "all-American" girl, and paid $1,200 an hour for a two-hour booking.
"He paid in cash," she said. "The first girl I sent to him said he was aggressive and didn't want to be back with him again," she added.
Spitzer and Strauss-Kahn are not the only well known figures to be called out by Davis. In 2009, she said Yankees slugger Alex Rodriguez was a former client.
Davis was also a gubernatorial candidate in New York in 2010, and ran on a platform that centered around legalizing marijuana, prostitution and gay marriage.
