The most famous celeb rehab joint around is crazed over a story that claims Tara Reid's detox is a ploy to drum up business for the facility.
Star Magazine claims Promises Treatment Center is letting Reid rehab there for free -- with a luxury bedroom and a "no bag check policy."
Star claims attendance is down and profits are low, so Promises "asked around Hollywood to see who wanted to stay there for free."
Promises begs to differ: "The suggestion that Promises would search Hollywood for a celebrity who needs rehab in an effort to garner publicity is libelous, offensive and without merit."
The article has since been removed from Star's website. The mag didn't get back to us with a comment.
