A source says, "She seemed lost. She was trying to get James' attention, and he wouldn't give her anything. She was smoking a lot, not drinking in front of him, and then she went into a bedroom.
"From there, she went back to trying to get James' attention again, and he was ignoring her. She ran out crying."
Lohan was allegedly found passed out in a hotel hallway shortly after the incident.
The 20-year-old subsequently checked herself into the posh Wonderland rehabilitation center in the Hollywood Hills.
