Last month, the star of the films Just My Luck and Freaky Friday admitted that she was attending Alcoholics Anonymous meetings to try to control her drinking.
"I have made a proactive decision to take care of my personal health," Linds said through a spokeswoman. "I appreciate your well-wishes and ask that you please respect my privacy at this time."
