Mischa Barton – who called police with an undisclosed health problem this week – may be hitting another rough patch in her personal life, sources report.
"She has been dealing with a lot of personal issues," a pal says. "I don't know if she ever gave up the bad habits that got out of control a few years back."
The 23-year-old star of the CW's new series The Beautiful Life was scheduled to attend the premiere of her movie Homecoming Thursday in New York City but remained at Cedars-Sinai Medical Center in Los Angeles under psychiatric hold.
That's right, the Britney Spears hold.
"I wish Mischa all the best. First and foremost, we want her to get healthy," Homecoming producer Austin Stark told People. "It's obvious we'd like her to support the movie and be here with us, but we hope she gets better."
5150: Troubled Mischa Barton is being held on psychiatric hold in L.A.
Her rep declined to comment on the report of her in the psych ward, but said, "Mischa has been hospitalized per the recommendation of her doctor and resting."
Her hospitalization comes two years after Barton was also hospitalized in May 2007 after feeling ill at a friend's Memorial Day barbeque. It was the start of what would become several months of both legal and personal troubles for Mischa.
Back in December 2007, Barton was arrested for DUI, marijuana possession and driving without a license after police spotted her straddling two lanes of traffic while under the influence of alcohol, according to authorities.
Later that year, the actress split from her musician boyfriend Taylor Locke after dating him for a couple of months. In late 2008, Barton began dating another rocker, The Kooks' Luke Pritchard, but called it quits in March.
She has most recently been linked to Noel Fielding.
The star has also had to fend off celebrity gossip reports after photos surfaced showing a thinner Barton, prompting speculation about her weight and health.
