Her attorney filed a mistrial motion Friday, and the issue was briefly argued Bucks County court. Ultimately, the judge denied the request.
Finkelstein faces sentencing next Thursday.
Back in March, a jury found Finkelstein guilty of attempted prostitution, but not guilty of prostitution.

Police say the investigation began after Finkelstein posted an ad on the website Craigslist.
