Brace Yourself for Jeff Conaway

2/6/2008 2:00 PM PST BY TMZ STAFF
"Celebrity Rehab" patient Jeff Conaway -- Kenickie from "Grease" -- showed up to the Ivy yesterday looking a hot mess -- his entire chest a monstrosity of braces.


Conaway, who snapped a bone in his spine while lifting boxes last year, told TMZ he's had four back surgeries since -- and may even be going in for another. Getting hooked on the painkillers is no longer a problem for the former rehab resident ... he says his dosages are fully supervised.
