No. Not from another AA class. Though that is probably true too. She was absent from her birthday bash at Las Palmas Hotel where a shit load of friends showed up to wish her happy birthday. I guess she didn't wanna be tempted to drink and get more time behind bars so instead she just had a small, private party with the Hotel's owners and popped her little heroin pills. Way to party Lohan. You know how to get down old school.
