Eva Mendes has been getting help for a substance abuse problem at Cirque Lodge rehab facility. She has reportedly been at Cirque, where Lindsay Lohan received treatment last year, for several weeks.

Her publicist 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 proactively 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 Ghost Rider star was just signed as the new face of Calvin Klein Fragrances. The ad campaign is set to debut in Fall 2008.
