Although Michael Lohan has been planning on opening a rehab center of his own, RumorFix has learned that Lindsay Lohan's dad is checking into Celebrity Rehab.

Our insider says the 50-year-old's drugs of choice are cocaine and alcohol, and although he's been telling people he's been sober for six years, we are told that is not the case.

Lohan, who has been in rehab multiple times, also spent three years in jail during the 1990s. RumorFix has learned that host Dr. Drew Pinsky will delve into the trauma he received behind bars, and his Post Traumatic Stress Syndrome.

Come payday, Lohan will take home a check for $180,000.
