If Nick Velasquez knew that she didn’t have the right to drive, then why didn’t he stop her (since September 2006)?

Los Angeles prosecutors said Thursday they will ask a judge to revoke Paris Hilton’s probation in a reckless driving case, a move that could lead to a jail term.

The decision followed an investigation into whether the hotel heiress violated terms of her probation by driving last month with a suspended license.

“We’re confident we have sufficient evidence to prove that her license was suspended and that she had knowledge of that suspension,” said Nick Velasquez, a spokesman for the city attorney’s office.

Hilton could face up to 90 days in jail if a judge finds she violated her probation, he said.

Velasquez declined to elaborate on the evidence, citing an ongoing investigation.

In January, Hilton pleaded no contest to alcohol-related reckless driving stemming from a Sept. 7 arrest in Hollywood and was sentenced to 36 months probation, alcohol education and $1,500 in fines.

Hilton was pulled over on Sunset Boulevard on Feb. 28. Police said they saw her blue Bentley Continental GTC speeding with its headlights off. She was ticketed for misdemeanor driving with a suspended license.

Hilton’s spokesman Elliot Mintz said that the time that she was not aware that her license was suspended.

Mintz did not immediately return a call seeking comment Thursday.

He declined to comment Thursday.

“The situation is being handled by Paris’ attorneys. It would not be appropriate for us to say anything further at this time,” Mintz said.

A call to Hilton’s attorney, Howard Weitzman, was not immediately returned.
