Hard-partying Lindsay Is Now "Under Control"

Though but a few days into her stay at the Wonderland Center addiction-treatment facility, Lindsay Lohan is already reaping results. "She's been sending text messages from rehab saying she's the happiest she has ever been," a pal tells People. "She seems under control right now." As Lohan bids to stop her binging, production on her film I Know Who Killed Me, for which she was training as a pole dancer, has stopped, and she has even scratched plans to hit the Sundance Film Festival swag-and-swig circuit.
