Mischa Barton has apparently been given the all-clear.
The former O.C. star spent about two hours in a Los Angeles-area hospital over the weekend, after falling ill at Nicole Richie's Memorial Day barbecue.
Barton's publicist says the starlet suffered an adverse reaction after consuming a few cocktails on top of the prescription antibiotics she was taking for a persistent case of bronchitis.
"She is fine now," said a statement from publicist Leslie Sloane Zelnik. The statement said Barton left Tuesday for an undisclosed overseas location to begin work on a new movie.
No further details were available regarding her condition, but a source told TMZ that the 21-year-old Barton was "resting comfortably" shortly after being admitted to Sherman Oaks Hospital and that her mother and sister were by her side throughout.
The star of the upcoming period romance Virgin Territory has reportedly been battling bronchitis for the past several weeks, appearing under the weather in Cannes, Paris and London.
In a radio interview with E!'s Ryan Seacrest Wednesday, Richie, who hosted the bash at a friend's house, said she was not there when Barton fell ill because she was making a run to the grocery store at the time.
"She's good. She just mixed antibiotics and alcohol and got sick," Richie said.
Since the party, the Simple Life star has been busy doing damage control on her own behalf after the intentionally silly party invitation she sent out to friends fell into the wrong set of tabloid-editing hands.
"My fellow Americans it's that time of year to celebrate our country by drinking massive amounts of beer," the invitation began.
"Let's stand together as one, live the American dream/Take shots, pass out, & wake up with our pants ripped open at the seems/Let's glorify this day in your sluttiest tops and your tightest pair of tsubi jeans/Even though we have no [expletive] clue what Memorial Day really means!!"
Followed by this addendum: "There will be a scale at the front door. No girls over 100 pounds allowed in. Start starving yourself now. See you all then!!!"
Richie was unapologetic about the invite, telling Seacrest it was meant to be funny and was never meant to become public.
"It's a private email. I'm sending it to my friends as a joke. I didn't mean to make it public and I have every right to say what I want to my friends," she said.
"It's not that deep. I wanted to write something that rhymes. I don't even know what to say about it. I'm not a serious person at all and no one thinks that I am."
Her rep, Nicole Perna, backed her up, stating: "This invitation was sent via email to her friends who understand that she was responding in a joking manner to the constant untruths printed about her in the media.
"Her reference to Memorial Day was in no way meant to offend anyone but was simply an expression of her distaste for the current situation."
Richie was at a loss as to which of the many friends on her invite list forwarded her missive on to unintended recipients.
"It really makes me question who I trust in my life," she said.
