Lindsay Lohan's New Mug Shot -- If Looks Could Kill

Lindsay Lohan has just been booked by the Santa Monica police ... which means ... SHE HAS A BRAND NEW MUG SHOT ... and she does not look happy about it.

Lindsay was ordered to turn herself in for booking after pleading "no contest" Monday to the charge of giving false information to a police officer and reckless driving, stemming from her PCH car crash last summer.

By our count this is mug shot #6, that we've seen. Another was taken in NYC last year, but since NYPD doesn't release mug shots ... we got robbed

Lindsay was released moments after posing for her latest close-up.

As we reported, Lindsay was sentenced to 90 days in a lockdown rehab facility ... but that won't begin until after a hearing on May 2nd.

The shot marks Lindsay's 5 billionth mug shot ... if you recall, she also has mug shots from the time she was arrested for shoplifting, DUI, drug possession, etc, etc, etc, etc.
