Reid in Rehab, Won't Say Why

Actress Tara Reid checked herself into rehab in Los Angeles this week, People reports. She entered the facility preferred by Britney Spears—Promises Treatment Center—and did not reveal through a rep why she sought help. "She checked in herself," a friend said. "It was her decision."

Reid, who started a fashion line 3 months ago, has filled gossip blogs with tales of her high-octane lifestyle. But she recently said she called it quits. "I had fun," she said. "I ate and drank whatever. I dated a million guys, but I'm so happy with where I'm at right now. I don't need to do anything anymore." (More rehab stories.)
