Mischa Barton jetted off yesterday for Russia - which isn't far enough away from her ex-boyfriend Cisco Adler, as far as her parents are concerned.
The stunning former star of The OC gave her parents, Paul Marsden Barton and Nuala Quinn, quite a scare on Memorial Day when she was rushed by ambulance to California's Sherman Oaks Hospital after a party.
Barton had "an allergic reaction" after combining antibiotics (which she was taking for bronchitis) with booze, according to her publicist, who says her client was not taking mushrooms.
Just read the last sentence again, will you?
Mischa Barton did spend over a half hour in the bathroom at the party. And she was in a state of undress when she arrived at the emergency room, according to a source.
Now, if this were Kristin Cavallari in a state of undress at the ER, we're guessing none of the male orderlies would be complaining.
But this is Mischa we're talking about.
The one good thing that happened to Mischa Barton that day was the mistake made by the paparazzi, which set up shop outside the wrong hospital.
Barton's parents met her at the hospital - the correct one - to find their drugged-up daughter making a frantic phone call... to the Cisco Kid.
We're talking about Cisco Adler.
"They were angry about her condition," says a spy. "When they left the room, she ran to the phone and tried to call Cisco Adler," whom she supposedly broke up with months ago.
Hey, sometimes you wanna see Cisco Adler naked and sometimes you don't.
It's no secret that Barton's parents are not the biggest fans of the hard-partying, sometimes nude rocker best known to Internet surfers for... well, being a D-list rock star who likes being nude and partying.
"Her dad came back into the room, and heard Mischa Barton deliriously saying, 'Cisco, Cisco,'" says a New York Daily News source.
"Her dad freaked out. She put the phone down, but he yelled at the staff about letting her use the phone."
Wonder if Cisco's ex-fiancee, Kimberly Stewart, also makes such frantic calls.
Either way, after getting some IV fluids, Barton was sent on her merry way.
The experience should help the genuinely talented beauty avoid the excesses of Paris Hilton and Nicole Richie, who were at the same party.
Since the weekend, she's been getting ready for her untitled movie, for which she's been learning the Russian language.
They don't speak that in Kazakhstan, but our guess is that Borat would still sleep with Barton... or any other woman with a pulse.
