The notorious party girl decided to stay in last night after arriving at LAX around 7 pm. We waited outside her hotel to escort her to the club of her choice, but she stood us up!

Now we're on standby, waiting to see if Ms. Lohan will make an attempt to fulfill her court-ordered duties by attending her drug and alcohol program at Right On today, ahead of her hearing on Monday. It's 9:35 am PT -- let the countdown begin!
