This year, Lindsay Lohan has decided to give thanks for all her, um, good fortune in our fair city. The 21-year-old actress, who spent a few minutes in an L.A. jail last week for a pre-rehab dustup with the law, was spotted supping at Cipriani with her mother, Dina, and beaux du jour, Riley Giles. By the look on Ms. Lohan’s face in one lucky paparazzo’s snapshot, she was either shocked by the eatery’s $50 fritto misto or miffed at the snooping photog. (At least tomorrow over turkey, LiLo can give thanks that her mother isn’t starring in her own reality T.V. show!) Whatever the case, Ms. Lohan is apparently shacking up for the holiday at the Ritz Carlton on Central Park South, where she flashed the Transom a few months back.
