A horse racing tweet prompted prosecutors to halt a court hearing at which a lawyer for '70s heartthrob David Cassidy was supposed to accept a plea deal on the singer's behalf.

Cassidy was charged last summer with driving while intoxicated in the town of Schodack, near Albany. Because he lives in Florida, prosecutors agreed to let his lawyer appear in court for him Wednesday.

But a tweet by the New York Racing Association said Cassidy, 64, was at Saratoga Race Course, 40 miles north of Schodack.

A prosecutor told The Daily Gazette of Schenectady that officials were "disturbed" to learn Cassidy was nearby but apparently unable to appear. Cassidy's lawyer said his client may not have known the timing of his court date.

A new court date is being scheduled.

Cassidy appeared in TV's "The Partridge Family" from 1970 to 1974 and was a recording star and teen idol.
