“She has been dealing with a lot of personal issues,” a pal tells PEOPLE about the actress who has been spotted club hopping in L.A. and London the past few months. “I don’t know if she really ever gave up some of the bad habits that had gotten out of control a couple years back.”
The 23-year-old actress was scheduled to attend the premiere of her movie Homecoming Thursday night in New York City but remained at Cedars-Sinai Medical Center in Los Angeles where she was reportedly placed under psychiatric hold.
“I wish her all the best. First and foremost, we want her to get healthy again,” Homecoming producer Austin Stark tells PEOPLE. “It’s obvious we’d like her to support the movie and be here, but we hope she gets better.”
And of shooting Homecoming with Barton in Pittsburgh, Stark says, “When she was on-set, she acted like a professional. I honestly had no complaints. She struck me as a nice young girl, she never said anything mean to anyone, and she wasn’t late on-set or anything like that.”
