The "Law & Order: SVU" star called reports that the former "The Beautiful Life: TBL" was unprofessional while filming the NBC drama on Monday in New York "fiction."
The star then turned to Access' cameras, declaring, "This gossip is fiction!"
The New York Daily News' Gatecrasher column previously claimed Mischa had "badly bombed" during filming of a guest spot as a prostitute on the NBC crime show.
