According to People, the star is "doing well" at the Promises Treatment Facility in Malibu, but earlier on Sunday, the mag quoted a source as saying Tara had checked out on Saturday. The quote has since been removed.

The star has been at Promises for under a month. A rep for the facility had no comment when reached by Access.

The mag claim that the center is struggling with the economy and was using Tara to help them drum up publicity - was also denied.
