A judge said Tuesday that Gristina will be sentenced Nov. 20 to time served and probation as part of a plea deal. The judge warned the Scotland-born woman she could also be deported.

Gristina was arrested in February and spent four months in jail before being released on $250,000 bond in June.

The charge stemmed from a July 2011 tryst that authorities say she arranged involving two women and an officer posing as a client.

Prosecutors say Gristina had a roster of wealthy, well-placed clients and boasted of law-enforcement connections during 15 years in a business that made her millions.

She had said she was merely starting a dating service.
