Ted Williams entered a rehab clinic thursday and they have boosted security to top-notch levels so that nosy-a$$ media can’t be all in the recovery Kool-Aid.

According to TMZ reports:

The rehab center where “Golden Voice” Ted Williams is seeking treatment has already gone into lockdown mode — bringing in extra security to make sure their most famous patient can stay focused.

TMZ has learned Williams checked in to Origins Recovery Center in South Texas around 10:00 PM Thursday night … where officials have also added additional screen paneling to block the paparazzi.

We’re told the average cost of a three-month stay runs around $49,000 … and Williams is on an all-expenses paid “scholarship.” We’re told Dr. Phil is not the benefactor.

No word on how long Williams plans to stay at the center.

Damn, they treating’ ol’ Ted Willy like he’s Barry O or somebody…play on playa.
