"It's 3:51 am -- do you know where Lindsay Lohan is?" She had just left a pool party at Teddy's at the Roosevelt Hotel in Hollywood and was being chauffeured around town by girlfriend (can we safely say that now? and i don't mean a friend who's a girl ...) Samantha Ronson.

The couple stopped for gas before heading home at 4:30 am and our photog spied Lindsay passed out in the passenger's seat.

Sad ...
