Mischa Barton has her parents worried about her following in the foot steps of some of her party friends such as Lindsay Lohan who went into rehab last week and Paris Hilton who was put in jail.
The 21-year-old "O.C." star gave her parents a scare on Memorial Day weekend when she collapsed after suffering a bad reaction from accidentally mixing antibiotics and alcohol. She was rushed to a Los Angeles hospital where doctors ordered her to rest.
Grazia, a British magazine, reported a source told them "Mischa's family is worried she is hanging around with the wrong kind of people because a lot of them are headed to rehab."
"Mischa doesn't really hang out with her old friends the way she used to and the people she's been spending time with - Lindsay, Paris and Nicole - have them totally freaked out," the source said.
Mischa’s younger sister Hania, 19, was put in rehab in February for her addiction to prescription painkillers.
"The last thing her family wants is for her to turn into some Hollywood party girl," a source says.
