The party's over. Lindsay Lohan was ordered by a Beverly Hills judge on Monday to wear a alcohol monitoring device and also to submit to weekly random drug testing.

If Lohan doesn’t comply with the order, she could face serious jail time. That's the kind of ruling that casts a serious pall over her hard partying lifestyle.

Yet again, of course, Lohan was ten minutes late to court and according to onlookers looked scared out of her mind.

According to her lawyer, who was pleading that the star could not possibly wear the monitoring device, Lohan had several photo shoots scheduled and a movie coming up in Texas. But the judge ignored the request and ruled that Lohan was not allowed to leave the state of California.

Lohan is now free on $100,000 bail pending a July 6 probation-violation hearing. If she’s found in violation, Lohan could face jail time.
