The $3,250-a-week center has the 27-year-old What I Like About You star teamed up with 15 other people to do daily exercises (including snowshoeing), as well as attend lectures on nutrition.

Bynes, who has been recovering at her parents' home, hit the snow before beginning school at the Fashion Institute of Design and Merchandising in Orange County, Calif. This all comes after the actress was forcibly hospitalized back in July following a driveway fire incident. She was later moved to a treatment center in Malibu, Calif., and was released in Dec. 2013. Her mother Lynn remains in indefinite control over Bynes' finances and well-being.
