Actress Eva Mendes has shocked fans by checking into rehab to treat a drug addiction problem. Her management have confirmed the glamorous star, who has been applauded for her clean-living and healthy body attitude, has been at Cirque Lodge Rehab for several weeks. Her representative released a statement saying: "Eva has been working hard for the past year and made a positive decision to take some much-needed time off to pro-actively attend to some personal issues that, while not critical, she felt deserved some outside professional support. "Out of respect for Eva's privacy, we do not wish to discuss further details." The 33-year-old star of We Own the Night has just been named the new face of Calvin Klein and a stint in the favoured rehab centre of Lindsay Lohan is not likely do her career any favours. Eva, who has also starred in films such as Hitch with Will Smith and Training Day with Denzel Washington, is a former face of cosmetics giant Revlon. Her management have not revealed how long she will be receiving treatment for in Utah.
