Actress Lindsay Lohan voluntarily checked herself into rehab on Tuesday for the fifth time in three years, celebrity news websites reported.
The actress' father, Michael, confirmed the reports. "Yea she definitely has (gone back to rehab)," he told TODAYshow.com's Courtney Hazlett via e-mail. "Can't discuss the location."
TMZ.com and celebrity photo news agency X17online.com said that Lohan, 24, checked into a rehabilitation center in southern California late Monday night and was expected to stay there until an Oct. 22 court hearing.
Lohan's lawyer did not immediately return calls for comment.
E! Online is reporting that it is not immediately clear where Lohan is seeking treatment but that sources told the website over the weekend that the Betty Ford Center near Palm Springs, Calif., was a prime option.
Lohan's mom, Dina, and manager Lou Taylor are looking into establishing a conservatorship when Lindsay checks out, Michael Lohan also told E! News.
The decision by the star of movies "Freaky Friday" and "Mean Girls" to go to rehab follows a chaotic summer of court appearances, rehab and jail time that has halted her bid to regain her once promising career.
Lohan did three stints in rehab in 2007 after admitting she was addicted to alcohol and drugs, and was released early from a fourth court-ordered stay in August.

Last week she was briefly taken back to jail after failing a court-ordered drug test, and she was ordered to wear a drug and alcohol monitoring device on her release.
Her problems stem from a 2007 conviction for drunk driving and cocaine possession, for which she has violated probation several times.
Lohan found fame as a child in the Disney movie "The Parent Trap" and became a sought-after teen celebrity after making films like "Herbie Fully Loaded". But she hit the Los Angeles and New York nightclub scenes hard, derailing her career as a serious actress.
