Old picture. New drama!

Even though she reportedly entered a treatment facility for her weight issues, Nicole Richie has a frightening incident while out partying in Los Angeles early Sunday morning!
There must have been something in everyone's supply this weekend, because everyone was acting crazy.
First, Lohan was displaying signs of paranoia at 6:45 AM, alone in her car.
And, now, our pals at TMZ are reporting that Nicole passed out at trendy hotspot Hyde just a few hours earlier, at 2 AM this Sunday!
Though we don't know what caused the Simple Life star to faint, the club's manager told Richie's pals that he was calling an ambulance, but her friends friends told him not make the call and that they would take the unconscious star to a hospital.
It's still unclear whether Nicole was admitted to the E.R., but she was seen being carried out of the club by her friends through the back door.
Before Richie collapsed, she was hanging out with Lindsay, whose own bizarre incident later that night/morning makes us question what was going on between the hard-partying friends.
Whatever went down, this is clearly a cry for help for both girls.
We hope they get the (medical) attention they both need!
